- Added new methods to wrapper.c for getting type declarations

* created a temporary logging solution

* added typedef struct parser

* cleanup

* restructured parsing

* restructured code

* header_parser: added struct parser, minor changes

- added type_extracter, moved typedeclaration_visitor into it
- cleanup imports

* parser: fixed type extraction

* updated libclang-example, minor fix for record_type spelling

* code_generator: added EnumClass, added test

* header_parser: added enum parsing

* header_parser: added typedef enums

* header_parser: extracted doxygen comment

- added clang_Cursor_getBriefCommentText_wrap in libclang bindings
- added comment extraction for functions, enums, structs

* Added args parsing and logging

- option for alternate yaml config
- added verbosity levels:[ all, fine, info, warning, severe ]

* config_provider: added output file option

* tests: added native_function_test

* code_generator: breaking change

- updated internal handling of type
- added support for NativeFunction type needed for creating typedefC
- updated tests, tool
- updated header_parser/type_extractor

* Added support for function pointers in bindings

- example/libclang-example: added clang_visitChildren_wrap method
- clang_bindings: added new methods getNumArgType, getArgType

* header_parser: changes, complete libclang_example

- completed libclang_example, all structs starting with CX
all functions starting with clang_ except those passing/returning structs b value
- added automatic typenaming to unnamed typedefs, unnamed function paramters

* minor changes

- code_generator: added factory Type constructor
- updated tests and code to prefer using factory type constructors
- added location methods to bindings

* header_parser: added support for multiple headers, header-filters

* header_parser: add structs used by functions

- updated example/libclang to auto add IndexerCallback struct
as its used in a function
- structs are now added automatically if they are returned or
passed in to a function (if struct type is parsed by extractor
it automatically adds it)

* config_provider: added sizemap for char, ints

* tests: added simple tests for functions

- test with supported types
- added automatic argument naming for functions in code_gen if they are null or only whitspaces
- code_gen_tests: only create debug file on test failure

* config_provider: added sort option to config

- updated libclang-example to use this
- renamed generated file names
- renamed package name for example

* example: added new cJSON example, bug fix

- new cJSON example, parsing a json and comparing it to json parsed by dart:convert
- bug fix: shouldInclude.* functions not adding to seen Set in includer

* linter bug fix, updated code for warnings

* minor changes

- documentation updates
- code_gen: wrong binding string type in metadata fix

* logging: improved log comments

* code_generator: removed global constants file

- lib prefixes are passed via writer now

* improved tests, minor changes

- improved header_parser_test
- updated named constructors of code_generator: Type

* header_parser: struct fields parsed

- all structs fields are excluded, if any field is struct by value or array
- added 2 functions using tool to clang bindings for parsing array element name, number
- updated libclang example
- added Broadtype.Array for code_gen (only used as indicator of type rn to exclude from parsing)

* parser: extract type from supported typdef

- Added config 'use-supported-typedefs'
- support for intptr_t
- updated test: native_function_bindings, added intptr_t

* header_parser: added workaround for array in struct

- updated libclang example

* fix: exclude array of struct in struct

* config_provider: revamped internal API

Reason: Multiple seperate things were added whenever a config spec was added to the tool
regarding-
1. validate yaml, detect unknown keys
2. tracking default value
3. extracting from map
4. Warning user if config is required and isnt provided

All this is now being managed at one place, A map of Spec is provided using
the getSpecs function, Spec has everything listed above
Adding a configuration is simply adding a Spec to the map returned by getSpecs
in config.dart

* Removed generated binding's dependency on package:ffi

- updated examples, tests
- changed Char_S type to Int8 (previously Utf8)

* temp: adding cmake

* WIP: cmakefile

* fix: loading dylib for other platforms

- updated validator, extractor
- updated examples
- config: changed libclang-dylib to libclang-dylib-folder

* Added build script for windows: tool/wrapped_libclang/build_dylib_windows

* Windows Testing

- Added build scripts(.bat files) for building dll for examples/tests
- Updated exmaple's input header globs to work on Windows (Globs on windows dont work if they start with "." or".."
- Used path package instead

* added warn about removing functions, minor changes

* config_provider: minor changes - sizemap, enum, comments

- Added enum to sizemap
- warn unknown subkeys in sizemap
- config option to disable dartdoc comment extraction

* fixed tests, minor changes

* Added warning for TU diagnostic errors

* header_parser: handling unimplemented types

- Added a BroadType.unimplemented, which can be used to determine and remove types
- Removing functions and struct members if unimplemented types are used (and show warning) (earlier exception was thrown)
- Added a flag to remove function with constant array passed as parameter

* update readme, comments

* update readme(s), linked todos to github issues

* added copyright notice to code files, update readme(s)

* Self hosting the tool: added libclang_config.yaml

- Removed clang_constants.dart file, all bindings are now in clang_bindings.dart

- Added build_dylib_macos script

* Replace platform based build scripts with build.dart

* Improved comments in accordance with styleguide

* config_provider: refactoring

* Added 3 lint rules

- prefer_final_fields
- prefer_final_locals
- prefer_final_in_for_each

* config_provider: made libclang_dylib_folder optional

User now has an option to provide a seperate folder containing the dynamic library
The default is to use the dynamic libraries in the tool/wrapped_libclang folder

* header_parser: removed file extension checks

User can provide any file path or glob matcher.
If clang can't parse a header, we print a severe log
and skip that header

* minor changes

* Updated warnings/error logs

* Minor changes

- Added test/native_function_test/build_test_dylib.dart
- Updated comments
- Added top level third_party folder
- Updated examples, test with fixed comments

* minor comment fix

/// AUTO GENERATED FILE, DO NOT EDIT.
///
/// Generated by `package:ffigen`.

* Updated build.dart, build_test_dylib.dart, Minor changes

 Experimental binding generator for [FFI](https://dart.dev/guides/libraries/c-interop)
 bindings.
+
+## Example
+
+For some header file _example.h_:
+```C
+int sum(int a, int b);
+```
+Add configurations to Pubspec File:
+```yaml
+ffigen:
+  output: 'generated_bindings.dart'
+  headers:
+    - 'example.h'
+```
+Output (_generated_bindings.dart_).
+```dart
+DynamicLibrary _dylib;
+
+/// Initialises dynamic library
+void init(DynamicLibrary dylib) {
+  _dylib = dylib;
+}
+
+int sum(int a,int b) {
+  return _sum(a,b);
+}
+
+final _dart_sum _sum = _dylib.lookupFunction<_c_sum, _dart_sum>('sum');
+
+typedef _c_sum = Int32 Function(Int32 a,Int32 b);
+
+typedef _dart_sum = int Function(int a,int b);
+```
+## Using this package
+- clone/download this repository.
+- Build it (see [building](#building)).
+- Add this package as dev_dependency in your `pubspec.yaml`.
+- Configurations must be provided in the pubspec.yaml file under the key `ffigen` (or directly under a seperate yaml file which when u specify it passing `--config filename` when running the tool)
+- Run the tool- `pub run ffigen:generate`.
+
+## Building
+A dynamic library for a wrapper to libclang needs to be generated as it is used by the parser submodule.
+
+#### ubuntu/linux
+1. Install libclangdev - `sudo apt-get install libclang-dev`.
+2. `cd tool/wrapped_libclang`, then run `dart build.dart`.
+
+#### Windows
+1. Install Visual Studio with C++ development support.
+2. Install LLVM.
+3. `cd tool\wrapped_libclang`, then run `dart build.dart`.
+
+#### MacOS
+1. Install LLVM.
+2. `cd tool/wrapped_libclang`, then run `dart build.dart`.
+
+## Trying out examples
+1. `cd examples/<example_u_want_to_run>`, Run `pub get`.
+2. Run `pub run ffigen:generate`.
+
+## Running Tests
+Dynamic library for some tests need to be built before running the examples.
+1. `cd test/native_functions_test`.
+2. Run `dart build_test_dylib.dart`.
+
+Run tests from the root of the package with `pub run test`.

+# cJson example
+
+Demonstrates generation of bindings for a C library called
+[cJson](https://github.com/DaveGamble/cJSON) and then using these bindings
+to parse some json.
+
+## Building the cJson dynamic library
+From the root of this repository -
+```
+cd third_party/cjson_library
+cmake .
+make
+```
+
+## Generating bindings
+At the root of this example (`example/c_json`), run -
+```
+pub run ffigen:generate
+```
+This will generate bindings in a file: [cjson_generated_bindings.dart](./cjson_generated_bindings.dart)
+
+## Running the example
+```
+dart main.dart
+```

+## Project Structure
+
+- `bin` - Contains generate.dart script which end user will execute.
+- `tool` - Contains script to generate LibClang bindings using Code_Generator submodule (dev use only).
+- `example` - Example projects which demonstrate generation of bindings for given C header files.
+- `lib/src/code_generator` - Generates binding files.
+- `lib/src/config_provider` - Holds configurations to be passed to other modules.
+- `lib/src/header_parser` - Parses header files, utilises clang_bindings.
+
+## Basic Workflow
+1. The User provides the location all the header files (as a list of globs or filepaths),
+For each header file, we create a translation unit and parse the `declarations` in it
+to the bindings.
+2. User can provide `header filters` to select which declaration from a particular header file should be added to the generated bindings. The can provide a list of header 'names' to include/exclude.
+We compare the header file name (not the exact path) to decide.
+The default behaviour is to include everything that's included when parsing a header.
+3. Use can provide Compiler options, which are passed to clang compiler as it is.
+4. All bindings are generated in a single file.
+
+# Code Details
+## Modules
+We are using libclang to parse header files.
+This project is roughly divided in 3 major modules -
+### code_generator
+Converts a library(all bindings) to an actual string representation.
+- Library (output of the header parser).
+- Writer (provides configurations for generating bindings).
+- Binding (base class for all bindings - Func, Struc, Global, EnumClass, etc).
+### config_provider
+This takes care of validating user config files, printing config warnings and errors,
+converting config.yaml to a format the header_parser can use.
+- Spec (represents a single config, which a user can provide in the config file).
+- Config (holds all the config which will be required by header parser).
+### header_parser
+Uses libclang to convert the header to a Library which is then used by code_generator.
+- clang_bindings (bindings to libclang which are used for parsing).
+- sub_parsers (each sub-parser parses a particular kind of declaration - struct, function, typedef, enum).
+- type_extractor (extracts types from variables, function parameters, return types).
+- includer (tells what should/shouldn't be included depending of config).
+- parser (Main Entrypoint) (creates translation units for all header files, and sets up parsing them).
+- translation_unit_parser (parses header files, splits declarations and feeds them to their respective sub_parsers).

 /// Perform code completion at a given location in a translation unit.

+/// This function performs code completion at a particular file, line, and

+/// performing syntax checking up to the location where code-completion has
+/// been requested. At that point, a special code-completion token is passed
+/// to the parser, which recognizes this token and determines, based on the
+/// current location in the C/Objective-C/C++ grammar and the state of
+/// semantic analysis, what completions to provide. These completions are
+/// returned via a new \c CXCodeCompleteResults structure.
+///
+/// Code completion itself is meant to be triggered by the client when the
+/// user types punctuation characters or whitespace, at which point the
+/// code-completion location will coincide with the cursor. For example, if \c p
+/// is a pointer, code-completion might be triggered after the "-" and then
+/// after the ">" in \c p->. When the code-completion location is after the ">",
+/// the completion results will provide, e.g., the members of the struct that
+/// "p" points to. The client is responsible for placing the cursor at the
+/// beginning of the token currently being typed, then filtering the results
+/// based on the contents of the token. For example, when code-completing for
+/// the expression \c p->get, the client should provide the location just after
+/// the ">" (e.g., pointing at the "g") to this code-completion hook. Then, the

Subject: [PATCH 010/276] [ffigen] Support for Prefix and Names in config.
 (#20)

- Support for global prefix and prefix replacement in functions/structs/enums
- Handles all internal name collisions (such as those between - dylib identifier, ffi import prefix, any typedefs generated, array helper classes, expanded array items, declarations, init function) if a collision occurs its suffixed by `_cr<int>`
- Added tests for prefixing and collisions

Subject: [PATCH 011/276] [ffigen] Added wrapper over lookUpbindings, fixed
 merge conflicts, migrated code (#25)

Closes #10.

Moves the functions from toplevel to a class to facilitate being able to use the bindings more flexibly.

* Replaced config init-function-name with name and description.
* Handled name conflicts - Function-Function, Typedef - Function - Struct/Enum.
* Updated examples and clang_bindings, Updated tests.

-/// Perform code completion at a given location in a translation unit.
-///
-/// This function performs code completion at a particular file, line, and
-/// column within source code, providing results that suggest potential
-/// code snippets based on the context of the completion. The basic model
-/// for code completion is that Clang will parse a complete source file,
-/// performing syntax checking up to the location where code-completion has
-/// been requested. At that point, a special code-completion token is passed
-/// to the parser, which recognizes this token and determines, based on the
-/// current location in the C/Objective-C/C++ grammar and the state of
-/// semantic analysis, what completions to provide. These completions are
-/// returned via a new \c CXCodeCompleteResults structure.
-///
-/// Code completion itself is meant to be triggered by the client when the
-/// user types punctuation characters or whitespace, at which point the
-/// code-completion location will coincide with the cursor. For example, if \c p
-/// is a pointer, code-completion might be triggered after the "-" and then
-/// after the ">" in \c p->. When the code-completion location is after the ">",
-/// the completion results will provide, e.g., the members of the struct that
-/// "p" points to. The client is responsible for placing the cursor at the
-/// beginning of the token currently being typed, then filtering the results
-/// based on the contents of the token. For example, when code-completing for
-/// the expression \c p->get, the client should provide the location just after
-/// the ">" (e.g., pointing at the "g") to this code-completion hook. Then, the
-/// client can filter the results based on the current token text ("get"), only
-/// showing those results that start with "get". The intent of this interface
-/// is to separate the relatively high-latency acquisition of code-completion
-/// results from the filtering of results on a per-character basis, which must
-/// have a lower latency.
-///
-/// \param TU The translation unit in which code-completion should
-/// occur. The source files for this translation unit need not be
-/// completely up-to-date (and the contents of those source files may
-/// be overridden via \p unsaved_files). Cursors referring into the
-/// translation unit may be invalidated by this invocation.
-///
-/// \param complete_filename The name of the source file where code
-/// completion should be performed. This filename may be any file
-/// included in the translation unit.
-///
-/// \param complete_line The line at which code-completion should occur.
-///
-/// \param complete_column The column at which code-completion should occur.
-/// Note that the column should point just after the syntactic construct that
-/// initiated code completion, and not in the middle of a lexical token.
-///
-/// \param unsaved_files the Files that have not yet been saved to disk
-/// but may be required for parsing or code completion, including the
-/// contents of those files.  The contents and name of these files (as
-/// specified by CXUnsavedFile) are copied when necessary, so the
-/// client only needs to guarantee their validity until the call to
-/// this function returns.
-///
-/// \param num_unsaved_files The number of unsaved file entries in \p
-/// unsaved_files.
-///
-/// \param options Extra options that control the behavior of code
-/// completion, expressed as a bitwise OR of the enumerators of the
-/// CXCodeComplete_Flags enumeration. The
-/// \c clang_defaultCodeCompleteOptions() function returns a default set
-/// of code-completion options.
-///
-/// \returns If successful, a new \c CXCodeCompleteResults structure
-/// containing code-completion results, which should eventually be
-/// freed with \c clang_disposeCodeCompleteResults(). If code
-/// completion fails, returns NULL.

-/// those files.  The contents and name of these files (as specified by
-/// CXUnsavedFile) are copied when necessary, so the client only needs to
-/// guarantee their validity until the call to this function returns.
-///
-/// \param num_unsaved_files the number of unsaved file entries in \p
-/// unsaved_files.
-///
-/// \param options A bitmask of options that affects how the translation unit
-/// is managed but not its compilation. This should be a bitwise OR of the
-/// CXTranslationUnit_XXX flags.
-///
-/// \param[out] out_TU A non-NULL pointer to store the created

-/// have changed (either on disk or as passed via \p unsaved_files). The
-/// source code will be reparsed with the same command-line options as it
-/// was originally parsed.
-///
-/// Reparsing a translation unit invalidates all cursors and source locations
-/// that refer into that translation unit. This makes reparsing a translation
-/// unit semantically equivalent to destroying the translation unit and then
-/// creating a new translation unit with the same command-line arguments.
-/// However, it may be more efficient to reparse a translation
-/// unit using this routine.
-///
-/// \param TU The translation unit whose contents will be re-parsed. The

-/// unsaved_files.
-///
-/// \param unsaved_files The files that have not yet been saved to disk
-/// but may be required for parsing, including the contents of
-/// those files.  The contents and name of these files (as specified by
-/// CXUnsavedFile) are copied when necessary, so the client only needs to
-/// guarantee their validity until the call to this function returns.
-///
-/// \param options A bitset of options composed of the flags in CXReparse_Flags.
-/// The function \c clang_defaultReparseOptions() produces a default set of
-/// options recommended for most uses, based on the translation unit.
-///
-/// \returns 0 if the sources could be reparsed.  A non-zero error code will be
-/// returned if reparsing was impossible, such that the translation unit is
-/// invalid. In such cases, the only valid call for \c TU is
-/// \c clang_disposeTranslationUnit(TU).  The error codes returned by this

+## Array-Workaround
+Fixed size array's in structs aren't currently supported by Dart. However we provide
+a workaround, using which array items can now be accessed using `[]` operator.
+
+Here's a C structure from libclang-
+```c
+typedef struct {
+  unsigned long long data[3];
+} CXFileUniqueID;
+```
+The generated code is -
+```dart
+class CXFileUniqueID extends ffi.Struct {
+  @ffi.Uint64()
+  int _unique_data_item_0;
+  @ffi.Uint64()
+  int _unique_data_item_1;
+  @ffi.Uint64()
+  int _unique_data_item_2;
+
+  /// Helper for array `data`.
+  ArrayHelper_CXFileUniqueID_data_level0 get data =>
+      ArrayHelper_CXFileUniqueID_data_level0(this, [3], 0, 0);
+}
+
+/// Helper for array `data` in struct `CXFileUniqueID`.
+class ArrayHelper_CXFileUniqueID_data_level0 {
+  final CXFileUniqueID _struct;
+  final List<int> dimensions;
+  final int level;
+  final int _absoluteIndex;
+  int get length => dimensions[level];
+  ArrayHelper_CXFileUniqueID_data_level0(
+      this._struct, this.dimensions, this.level, this._absoluteIndex);
+  void _checkBounds(int index) {
+    if (index >= length || index < 0) {
+      throw RangeError(
+          'Dimension $level: index not in range 0..${length} exclusive.');
+    }
+  }
+
+  int operator [](int index) {
+    _checkBounds(index);
+    switch (_absoluteIndex + index) {
+      case 0:
+        return _struct._unique_data_item_0;
+      case 1:
+        return _struct._unique_data_item_1;
+      case 2:
+        return _struct._unique_data_item_2;
+      default:
+        throw Exception('Invalid Array Helper generated.');
+    }
+  }
+
+  void operator []=(int index, int value) {
+    _checkBounds(index);
+    switch (_absoluteIndex + index) {
+      case 0:
+        _struct._unique_data_item_0 = value;
+        break;
+      case 1:
+        _struct._unique_data_item_1 = value;
+        break;
+      case 2:
+        _struct._unique_data_item_2 = value;
+        break;
+      default:
+        throw Exception('Invalid Array Helper generated.');
+    }
+  }
+}
+```
+
+## Limitations
+1. Multi OS support for types such as long. [Issue #7](https://github.com/dart-lang/ffigen/issues/7)
+2. Function's passing/returning structs by value are skipped. [Issue #3](https://github.com/dart-lang/ffigen/issues/3)
+3. Structs containing structs will have all their members removed. [Issue #4](https://github.com/dart-lang/ffigen/issues/4)
+
 ## Trying out examples
 1. `cd examples/<example_u_want_to_run>`, Run `pub get`.
 2. Run `pub run ffigen`.
 
 ## Running Tests
 Dynamic library for some tests need to be built before running the examples.
-1. `cd test/native_functions_test`.
+1. `cd test/native_test`.
 2. Run `dart build_test_dylib.dart`.
 
 Run tests from the root of the package with `pub run test`.

Subject: [PATCH 013/276] [ffigen] Fixes for running on MacOS (#32)

* Fixed null completeness warning by clang by adding `-Wno-nullability-completeness` to compiler-opts in examples and wrapper build.
* Fixed relative path not allowed in hardened programs error by using absolute path for loading dynamic library if available.

Subject: [PATCH 014/276] [ffigen] Added large tests, bug fixes (#33)

closes #29, closes #17

- Added large tests for Libclang, cJSON and SQLite #17.
- Bug fix: Nested parsing, added tests for nested parsing. Sub parsers now use a stack to hold information about current declaration.
- Bug fix: Unsupported operation error when finding dynamic library path on windows #29.
- Added property originalName to Binding.
- Config provider now throws ConfigError if a required config is missing. This fixes tests not running previously due to exit call in config provider.
- Updated libclang wrapper to support running from multiple isolates (fixes concurrent test running).

+ * base class, its protocols, or its categories' protocols, that has the same

+ * If no such method exists, the search continues to the class's superclass,

+ * corresponding method in the interface.
+ *
+ * For C++, a virtual member function overrides any virtual member
+ * function with the same signature that occurs in its base
+ * classes. With multiple inheritance, a virtual member function can
+ * override several virtual member functions coming from different
+ * base classes.
+ *
+ * In all cases, this function determines the immediate overridden
+ * method, rather than all of the overridden methods. For example, if
+ * a method is originally declared in a class A, then overridden in B
+ * (which in inherits from A) and also in C (which inherited from B),
+ * then the only overridden method returned from this function when

+ * been requested. At that point, a special code-completion token is passed
+ * to the parser, which recognizes this token and determines, based on the
+ * current location in the C/Objective-C/C++ grammar and the state of
+ * semantic analysis, what completions to provide. These completions are
+ * returned via a new \c CXCodeCompleteResults structure.
+ *
+ * Code completion itself is meant to be triggered by the client when the
+ * user types punctuation characters or whitespace, at which point the
+ * code-completion location will coincide with the cursor. For example, if \c p
+ * is a pointer, code-completion might be triggered after the "-" and then
+ * after the ">" in \c p->. When the code-completion location is after the ">",
+ * the completion results will provide, e.g., the members of the struct that
+ * "p" points to. The client is responsible for placing the cursor at the
+ * beginning of the token currently being typed, then filtering the results
+ * based on the contents of the token. For example, when code-completing for
+ * the expression \c p->get, the client should provide the location just after
+ * the ">" (e.g., pointing at the "g") to this code-completion hook. Then, the
+ * client can filter the results based on the current token text ("get"), only
+ * showing those results that start with "get". The intent of this interface
+ * is to separate the relatively high-latency acquisition of code-completion
+ * results from the filtering of results on a per-character basis, which must
+ * have a lower latency.
+ *
+ * \param TU The translation unit in which code-completion should
+ * occur. The source files for this translation unit need not be
+ * completely up-to-date (and the contents of those source files may
+ * be overridden via \p unsaved_files). Cursors referring into the
+ * translation unit may be invalidated by this invocation.
+ *
+ * \param complete_filename The name of the source file where code
+ * completion should be performed. This filename may be any file
+ * included in the translation unit.
+ *
+ * \param complete_line The line at which code-completion should occur.
+ *
+ * \param complete_column The column at which code-completion should occur.
+ * Note that the column should point just after the syntactic construct that
+ * initiated code completion, and not in the middle of a lexical token.
+ *
+ * \param unsaved_files the Files that have not yet been saved to disk
+ * but may be required for parsing or code completion, including the
+ * contents of those files.  The contents and name of these files (as
+ * specified by CXUnsavedFile) are copied when necessary, so the
+ * client only needs to guarantee their validity until the call to
+ * this function returns.
+ *
+ * \param num_unsaved_files The number of unsaved file entries in \p
+ * unsaved_files.
+ *
+ * \param options Extra options that control the behavior of code
+ * completion, expressed as a bitwise OR of the enumerators of the
+ * CXCodeComplete_Flags enumeration. The
+ * \c clang_defaultCodeCompleteOptions() function returns a default set
+ * of code-completion options.
+ *
+ * \returns If successful, a new \c CXCodeCompleteResults structure
+ * containing code-completion results, which should eventually be
+ * freed with \c clang_disposeCodeCompleteResults(). If code
+ * completion fails, returns NULL.

+** on error message strings returned through the 5th parameter of
+** sqlite3_exec() after the error message string is no longer needed.
+** ^If the 5th parameter to sqlite3_exec() is not NULL and no errors
+** occur, then sqlite3_exec() sets the pointer in its 5th parameter to
+** NULL before returning.
+**
+** ^If an sqlite3_exec() callback returns non-zero, the sqlite3_exec()
+** routine returns SQLITE_ABORT without invoking the callback again and
+** without running any subsequent SQL statements.
+**
+** ^The 2nd argument to the sqlite3_exec() callback function is the
+** number of columns in the result.  ^The 3rd argument to the sqlite3_exec()
+** callback is an array of pointers to strings obtained as if from

+** may be invoked even if the [sqlite3_vfs.xOpen] reported that it failed.  The
+** only way to prevent a call to xClose following a failed [sqlite3_vfs.xOpen]
+** is for the [sqlite3_vfs.xOpen] to set the sqlite3_file.pMethods element
+** to NULL.
+**
+** The flags argument to xSync may be one of [SQLITE_SYNC_NORMAL] or
+** [SQLITE_SYNC_FULL].  The first choice is the normal fsync().

+** and not its inode needs to be synced.

+** xLock() increases the lock. xUnlock() decreases the lock.
+** The xCheckReservedLock() method checks whether any database connection,
+** either in this process or in some other process, is holding a RESERVED,
+** PENDING, or EXCLUSIVE lock on the file.  It returns true
+** if such a lock exists and false otherwise.
+**
+** The xFileControl() method is a generic interface that allows custom
+** VFS implementations to directly control an open file using the
+** [sqlite3_file_control()] interface.  The second "op" argument is an
+** integer opcode.  The third argument is a generic pointer intended to
+** point to a structure that may contain arguments or space in which to
+** write return values.  Potential uses for xFileControl() might be
+** functions to enable blocking locks with timeouts, to change the
+** locking strategy (for example to use dot-file locks), to inquire
+** about the status of a lock, or to break stale locks.  The SQLite
+** core reserves all opcodes less than 100 for its own use.
+** A [file control opcodes | list of opcodes] less than 100 is available.
+** Applications that define a custom xFileControl method should use opcodes

+** CAPI3REF: Standard File Control Opcodes

+**
+** These integer constants are opcodes for the xFileControl method
+** of the [sqlite3_io_methods] object and for the [sqlite3_file_control()]
+** interface.
+**
+** <ul>
+** <li>[[SQLITE_FCNTL_LOCKSTATE]]
+** The [SQLITE_FCNTL_LOCKSTATE] opcode is used for debugging.  This
+** opcode causes the xFileControl method to write the current state of
+** the lock (one of [SQLITE_LOCK_NONE], [SQLITE_LOCK_SHARED],
+** [SQLITE_LOCK_RESERVED], [SQLITE_LOCK_PENDING], or [SQLITE_LOCK_EXCLUSIVE])
+** into an integer that the pArg argument points to. This capability
+** is used during testing and is only available when the SQLITE_TEST
+** compile-time option is used.
+**
+** <li>[[SQLITE_FCNTL_SIZE_HINT]]
+** The [SQLITE_FCNTL_SIZE_HINT] opcode is used by SQLite to give the VFS
+** layer a hint of how large the database file will grow to be during the
+** current transaction.  This hint is not guaranteed to be accurate but it
+** is often close.  The underlying VFS might choose to preallocate database
+** file space based on this hint in order to help writes to the database
+** file run faster.
+**
+** <li>[[SQLITE_FCNTL_SIZE_LIMIT]]
+** The [SQLITE_FCNTL_SIZE_LIMIT] opcode is used by in-memory VFS that
+** implements [sqlite3_deserialize()] to set an upper bound on the size
+** of the in-memory database.  The argument is a pointer to a [sqlite3_int64].
+** If the integer pointed to is negative, then it is filled in with the
+** current limit.  Otherwise the limit is set to the larger of the value
+** of the integer pointed to and the current database size.  The integer
+** pointed to is set to the new limit.
+**
+** <li>[[SQLITE_FCNTL_CHUNK_SIZE]]
+** The [SQLITE_FCNTL_CHUNK_SIZE] opcode is used to request that the VFS
+** extends and truncates the database file in chunks of a size specified
+** by the user. The fourth argument to [sqlite3_file_control()] should 
+** point to an integer (type int) containing the new chunk-size to use
+** for the nominated database. Allocating database file space in large
+** chunks (say 1MB at a time), may reduce file-system fragmentation and
+** improve performance on some systems.
+**
+** <li>[[SQLITE_FCNTL_FILE_POINTER]]
+** The [SQLITE_FCNTL_FILE_POINTER] opcode is used to obtain a pointer
+** to the [sqlite3_file] object associated with a particular database
+** connection.  See also [SQLITE_FCNTL_JOURNAL_POINTER].
+**
+** <li>[[SQLITE_FCNTL_JOURNAL_POINTER]]
+** The [SQLITE_FCNTL_JOURNAL_POINTER] opcode is used to obtain a pointer
+** to the [sqlite3_file] object associated with the journal file (either
+** the [rollback journal] or the [write-ahead log]) for a particular database
+** connection.  See also [SQLITE_FCNTL_FILE_POINTER].
+**
+** <li>[[SQLITE_FCNTL_SYNC_OMITTED]]
+** No longer in use.
+**
+** <li>[[SQLITE_FCNTL_SYNC]]
+** The [SQLITE_FCNTL_SYNC] opcode is generated internally by SQLite and
+** sent to the VFS immediately before the xSync method is invoked on a
+** database file descriptor. Or, if the xSync method is not invoked 
+** because the user has configured SQLite with 
+** [PRAGMA synchronous | PRAGMA synchronous=OFF] it is invoked in place 
+** of the xSync method. In most cases, the pointer argument passed with
+** this file-control is NULL. However, if the database file is being synced
+** as part of a multi-database commit, the argument points to a nul-terminated
+** string containing the transactions master-journal file name. VFSes that 
+** do not need this signal should silently ignore this opcode. Applications 
+** should not call [sqlite3_file_control()] with this opcode as doing so may 
+** disrupt the operation of the specialized VFSes that do require it.  
+**
+** <li>[[SQLITE_FCNTL_COMMIT_PHASETWO]]
+** The [SQLITE_FCNTL_COMMIT_PHASETWO] opcode is generated internally by SQLite
+** and sent to the VFS after a transaction has been committed immediately
+** but before the database is unlocked. VFSes that do not need this signal
+** should silently ignore this opcode. Applications should not call
+** [sqlite3_file_control()] with this opcode as doing so may disrupt the 
+** operation of the specialized VFSes that do require it.  
+**
+** <li>[[SQLITE_FCNTL_WIN32_AV_RETRY]]
+** ^The [SQLITE_FCNTL_WIN32_AV_RETRY] opcode is used to configure automatic
+** retry counts and intervals for certain disk I/O operations for the
+** windows [VFS] in order to provide robustness in the presence of
+** anti-virus programs.  By default, the windows VFS will retry file read,
+** file write, and file delete operations up to 10 times, with a delay
+** of 25 milliseconds before the first retry and with the delay increasing
+** by an additional 25 milliseconds with each subsequent retry.  This
+** opcode allows these two values (10 retries and 25 milliseconds of delay)
+** to be adjusted.  The values are changed for all database connections
+** within the same process.  The argument is a pointer to an array of two
+** integers where the first integer is the new retry count and the second
+** integer is the delay.  If either integer is negative, then the setting
+** is not changed but instead the prior value of that setting is written
+** into the array entry, allowing the current retry settings to be
+** interrogated.  The zDbName parameter is ignored.
+**
+** <li>[[SQLITE_FCNTL_PERSIST_WAL]]
+** ^The [SQLITE_FCNTL_PERSIST_WAL] opcode is used to set or query the
+** persistent [WAL | Write Ahead Log] setting.  By default, the auxiliary
+** write ahead log ([WAL file]) and shared memory
+** files used for transaction control
+** are automatically deleted when the latest connection to the database
+** closes.  Setting persistent WAL mode causes those files to persist after
+** close.  Persisting the files is useful when other processes that do not
+** have write permission on the directory containing the database file want
+** to read the database file, as the WAL and shared memory files must exist
+** in order for the database to be readable.  The fourth parameter to
+** [sqlite3_file_control()] for this opcode should be a pointer to an integer.
+** That integer is 0 to disable persistent WAL mode or 1 to enable persistent
+** WAL mode.  If the integer is -1, then it is overwritten with the current
+** WAL persistence setting.
+**
+** <li>[[SQLITE_FCNTL_POWERSAFE_OVERWRITE]]
+** ^The [SQLITE_FCNTL_POWERSAFE_OVERWRITE] opcode is used to set or query the
+** persistent "powersafe-overwrite" or "PSOW" setting.  The PSOW setting
+** determines the [SQLITE_IOCAP_POWERSAFE_OVERWRITE] bit of the
+** xDeviceCharacteristics methods. The fourth parameter to
+** [sqlite3_file_control()] for this opcode should be a pointer to an integer.
+** That integer is 0 to disable zero-damage mode or 1 to enable zero-damage
+** mode.  If the integer is -1, then it is overwritten with the current
+** zero-damage mode setting.
+**
+** <li>[[SQLITE_FCNTL_OVERWRITE]]
+** ^The [SQLITE_FCNTL_OVERWRITE] opcode is invoked by SQLite after opening
+** a write transaction to indicate that, unless it is rolled back for some
+** reason, the entire database file will be overwritten by the current 
+** transaction. This is used by VACUUM operations.
+**
+** <li>[[SQLITE_FCNTL_VFSNAME]]
+** ^The [SQLITE_FCNTL_VFSNAME] opcode can be used to obtain the names of
+** all [VFSes] in the VFS stack.  The names are of all VFS shims and the
+** final bottom-level VFS are written into memory obtained from 
+** [sqlite3_malloc()] and the result is stored in the char* variable
+** that the fourth parameter of [sqlite3_file_control()] points to.
+** The caller is responsible for freeing the memory when done.  As with
+** all file-control actions, there is no guarantee that this will actually
+** do anything.  Callers should initialize the char* variable to a NULL
+** pointer in case this file-control is not implemented.  This file-control
+** is intended for diagnostic use only.
+**
+** <li>[[SQLITE_FCNTL_VFS_POINTER]]
+** ^The [SQLITE_FCNTL_VFS_POINTER] opcode finds a pointer to the top-level
+** [VFSes] currently in use.  ^(The argument X in
+** sqlite3_file_control(db,SQLITE_FCNTL_VFS_POINTER,X) must be
+** of type "[sqlite3_vfs] **".  This opcodes will set *X
+** to a pointer to the top-level VFS.)^
+** ^When there are multiple VFS shims in the stack, this opcode finds the
+** upper-most shim only.
+**
+** <li>[[SQLITE_FCNTL_PRAGMA]]
+** ^Whenever a [PRAGMA] statement is parsed, an [SQLITE_FCNTL_PRAGMA] 
+** file control is sent to the open [sqlite3_file] object corresponding
+** to the database file to which the pragma statement refers. ^The argument
+** to the [SQLITE_FCNTL_PRAGMA] file control is an array of
+** pointers to strings (char**) in which the second element of the array
+** is the name of the pragma and the third element is the argument to the
+** pragma or NULL if the pragma has no argument.  ^The handler for an
+** [SQLITE_FCNTL_PRAGMA] file control can optionally make the first element
+** of the char** argument point to a string obtained from [sqlite3_mprintf()]
+** or the equivalent and that string will become the result of the pragma or
+** the error message if the pragma fails. ^If the
+** [SQLITE_FCNTL_PRAGMA] file control returns [SQLITE_NOTFOUND], then normal 
+** [PRAGMA] processing continues.  ^If the [SQLITE_FCNTL_PRAGMA]
+** file control returns [SQLITE_OK], then the parser assumes that the
+** VFS has handled the PRAGMA itself and the parser generates a no-op
+** prepared statement if result string is NULL, or that returns a copy
+** of the result string if the string is non-NULL.
+** ^If the [SQLITE_FCNTL_PRAGMA] file control returns
+** any result code other than [SQLITE_OK] or [SQLITE_NOTFOUND], that means
+** that the VFS encountered an error while handling the [PRAGMA] and the
+** compilation of the PRAGMA fails with an error.  ^The [SQLITE_FCNTL_PRAGMA]
+** file control occurs at the beginning of pragma statement analysis and so
+** it is able to override built-in [PRAGMA] statements.
+**
+** <li>[[SQLITE_FCNTL_BUSYHANDLER]]
+** ^The [SQLITE_FCNTL_BUSYHANDLER]
+** file-control may be invoked by SQLite on the database file handle
+** shortly after it is opened in order to provide a custom VFS with access
+** to the connection's busy-handler callback. The argument is of type (void**)
+** - an array of two (void *) values. The first (void *) actually points
+** to a function of type (int (*)(void *)). In order to invoke the connection's
+** busy-handler, this function should be invoked with the second (void *) in
+** the array as the only argument. If it returns non-zero, then the operation
+** should be retried. If it returns zero, the custom VFS should abandon the
+** current operation.
+**
+** <li>[[SQLITE_FCNTL_TEMPFILENAME]]
+** ^Applications can invoke the [SQLITE_FCNTL_TEMPFILENAME] file-control
+** to have SQLite generate a
+** temporary filename using the same algorithm that is followed to generate
+** temporary filenames for TEMP tables and other internal uses.  The
+** argument should be a char** which will be filled with the filename
+** written into memory obtained from [sqlite3_malloc()].  The caller should
+** invoke [sqlite3_free()] on the result to avoid a memory leak.
+**
+** <li>[[SQLITE_FCNTL_MMAP_SIZE]]
+** The [SQLITE_FCNTL_MMAP_SIZE] file control is used to query or set the
+** maximum number of bytes that will be used for memory-mapped I/O.
+** The argument is a pointer to a value of type sqlite3_int64 that
+** is an advisory maximum number of bytes in the file to memory map.  The
+** pointer is overwritten with the old value.  The limit is not changed if
+** the value originally pointed to is negative, and so the current limit 
+** can be queried by passing in a pointer to a negative number.  This
+** file-control is used internally to implement [PRAGMA mmap_size].
+**
+** <li>[[SQLITE_FCNTL_TRACE]]
+** The [SQLITE_FCNTL_TRACE] file control provides advisory information
+** to the VFS about what the higher layers of the SQLite stack are doing.
+** This file control is used by some VFS activity tracing [shims].
+** The argument is a zero-terminated string.  Higher layers in the
+** SQLite stack may generate instances of this file control if
+** the [SQLITE_USE_FCNTL_TRACE] compile-time option is enabled.
+**
+** <li>[[SQLITE_FCNTL_HAS_MOVED]]
+** The [SQLITE_FCNTL_HAS_MOVED] file control interprets its argument as a
+** pointer to an integer and it writes a boolean into that integer depending
+** on whether or not the file has been renamed, moved, or deleted since it
+** was first opened.
+**
+** <li>[[SQLITE_FCNTL_WIN32_GET_HANDLE]]
+** The [SQLITE_FCNTL_WIN32_GET_HANDLE] opcode can be used to obtain the
+** underlying native file handle associated with a file handle.  This file
+** control interprets its argument as a pointer to a native file handle and
+** writes the resulting value there.
+**
+** <li>[[SQLITE_FCNTL_WIN32_SET_HANDLE]]
+** The [SQLITE_FCNTL_WIN32_SET_HANDLE] opcode is used for debugging.  This
+** opcode causes the xFileControl method to swap the file handle with the one
+** pointed to by the pArg argument.  This capability is used during testing
+** and only needs to be supported when SQLITE_TEST is defined.
+**
+** <li>[[SQLITE_FCNTL_WAL_BLOCK]]
+** The [SQLITE_FCNTL_WAL_BLOCK] is a signal to the VFS layer that it might
+** be advantageous to block on the next WAL lock if the lock is not immediately
+** available.  The WAL subsystem issues this signal during rare
+** circumstances in order to fix a problem with priority inversion.
+** Applications should <em>not</em> use this file-control.
+**
+** <li>[[SQLITE_FCNTL_ZIPVFS]]
+** The [SQLITE_FCNTL_ZIPVFS] opcode is implemented by zipvfs only. All other
+** VFS should return SQLITE_NOTFOUND for this opcode.
+**
+** <li>[[SQLITE_FCNTL_RBU]]
+** The [SQLITE_FCNTL_RBU] opcode is implemented by the special VFS used by
+** the RBU extension only.  All other VFS should return SQLITE_NOTFOUND for
+** this opcode.  
+**
+** <li>[[SQLITE_FCNTL_BEGIN_ATOMIC_WRITE]]
+** If the [SQLITE_FCNTL_BEGIN_ATOMIC_WRITE] opcode returns SQLITE_OK, then
+** the file descriptor is placed in "batch write mode", which
+** means all subsequent write operations will be deferred and done
+** atomically at the next [SQLITE_FCNTL_COMMIT_ATOMIC_WRITE].  Systems
+** that do not support batch atomic writes will return SQLITE_NOTFOUND.
+** ^Following a successful SQLITE_FCNTL_BEGIN_ATOMIC_WRITE and prior to
+** the closing [SQLITE_FCNTL_COMMIT_ATOMIC_WRITE] or
+** [SQLITE_FCNTL_ROLLBACK_ATOMIC_WRITE], SQLite will make
+** no VFS interface calls on the same [sqlite3_file] file descriptor
+** except for calls to the xWrite method and the xFileControl method
+** with [SQLITE_FCNTL_SIZE_HINT].
+**
+** <li>[[SQLITE_FCNTL_COMMIT_ATOMIC_WRITE]]
+** The [SQLITE_FCNTL_COMMIT_ATOMIC_WRITE] opcode causes all write
+** operations since the previous successful call to 
+** [SQLITE_FCNTL_BEGIN_ATOMIC_WRITE] to be performed atomically.
+** This file control returns [SQLITE_OK] if and only if the writes were
+** all performed successfully and have been committed to persistent storage.
+** ^Regardless of whether or not it is successful, this file control takes
+** the file descriptor out of batch write mode so that all subsequent
+** write operations are independent.
+** ^SQLite will never invoke SQLITE_FCNTL_COMMIT_ATOMIC_WRITE without
+** a prior successful call to [SQLITE_FCNTL_BEGIN_ATOMIC_WRITE].
+**
+** <li>[[SQLITE_FCNTL_ROLLBACK_ATOMIC_WRITE]]
+** The [SQLITE_FCNTL_ROLLBACK_ATOMIC_WRITE] opcode causes all write
+** operations since the previous successful call to 
+** [SQLITE_FCNTL_BEGIN_ATOMIC_WRITE] to be rolled back.
+** ^This file control takes the file descriptor out of batch write mode
+** so that all subsequent write operations are independent.
+** ^SQLite will never invoke SQLITE_FCNTL_ROLLBACK_ATOMIC_WRITE without
+** a prior successful call to [SQLITE_FCNTL_BEGIN_ATOMIC_WRITE].
+**
+** <li>[[SQLITE_FCNTL_LOCK_TIMEOUT]]
+** The [SQLITE_FCNTL_LOCK_TIMEOUT] opcode is used to configure a VFS
+** to block for up to M milliseconds before failing when attempting to 
+** obtain a file lock using the xLock or xShmLock methods of the VFS. 
+** The parameter is a pointer to a 32-bit signed integer that contains
+** the value that M is to be set to. Before returning, the 32-bit signed
+** integer is overwritten with the previous value of M.
+**
+** <li>[[SQLITE_FCNTL_DATA_VERSION]]
+** The [SQLITE_FCNTL_DATA_VERSION] opcode is used to detect changes to
+** a database file.  The argument is a pointer to a 32-bit unsigned integer.
+** The "data version" for the pager is written into the pointer.  The
+** "data version" changes whenever any change occurs to the corresponding
+** database file, either through SQL statements on the same database
+** connection or through transactions committed by separate database
+** connections possibly in other processes. The [sqlite3_total_changes()]
+** interface can be used to find if any database on the connection has changed,
+** but that interface responds to changes on TEMP as well as MAIN and does
+** not provide a mechanism to detect changes to MAIN only.  Also, the
+** [sqlite3_total_changes()] interface responds to internal changes only and
+** omits changes made by other database connections.  The
+** [PRAGMA data_version] command provides a mechanism to detect changes to
+** a single attached database that occur due to other database connections,
+** but omits changes implemented by the database connection on which it is
+** called.  This file control is the only mechanism to detect changes that
+** happen either internally or externally and that are associated with
+** a particular attached database.
+**
+** <li>[[SQLITE_FCNTL_CKPT_START]]
+** The [SQLITE_FCNTL_CKPT_START] opcode is invoked from within a checkpoint
+** in wal mode before the client starts to copy pages from the wal
+** file to the database file.
+**
+** <li>[[SQLITE_FCNTL_CKPT_DONE]]
+** The [SQLITE_FCNTL_CKPT_DONE] opcode is invoked from within a checkpoint
+** in wal mode after the client has finished copying pages from the wal
+** file to the database file, but before the *-shm file is updated to
+** record the fact that the pages have been checkpointed.

+/*
+** CAPI3REF: OS Interface Object
+**
+** An instance of the sqlite3_vfs object defines the interface between
+** the SQLite core and the underlying operating system.  The "vfs"
+** in the name of the object stands for "virtual file system".  See
+** the [VFS | VFS documentation] for further information.
+**
+** The VFS interface is sometimes extended by adding new methods onto
+** the end.  Each time such an extension occurs, the iVersion field
+** is incremented.  The iVersion value started out as 1 in
+** SQLite [version 3.5.0] on [dateof:3.5.0], then increased to 2
+** with SQLite [version 3.7.0] on [dateof:3.7.0], and then increased
+** to 3 with SQLite [version 3.7.6] on [dateof:3.7.6].  Additional fields
+** may be appended to the sqlite3_vfs object and the iVersion value
+** may increase again in future versions of SQLite.
+** Note that due to an oversight, the structure
+** of the sqlite3_vfs object changed in the transition from
+** SQLite [version 3.5.9] to [version 3.6.0] on [dateof:3.6.0]
+** and yet the iVersion field was not increased.
+**
+** The szOsFile field is the size of the subclassed [sqlite3_file]
+** structure used by this VFS.  mxPathname is the maximum length of
+** a pathname in this VFS.
+**
+** Registered sqlite3_vfs objects are kept on a linked list formed by
+** the pNext pointer.  The [sqlite3_vfs_register()]
+** and [sqlite3_vfs_unregister()] interfaces manage this list
+** in a thread-safe way.  The [sqlite3_vfs_find()] interface
+** searches the list.  Neither the application code nor the VFS
+** implementation should use the pNext pointer.
+**
+** The pNext field is the only field in the sqlite3_vfs
+** structure that SQLite will ever modify.  SQLite will only access
+** or modify this field while holding a particular static mutex.
+** The application should never modify anything within the sqlite3_vfs
+** object once the object has been registered.
+**
+** The zName field holds the name of the VFS module.  The name must
+** be unique across all VFS modules.
+**
+** [[sqlite3_vfs.xOpen]]
+** ^SQLite guarantees that the zFilename parameter to xOpen
+** is either a NULL pointer or string obtained
+** from xFullPathname() with an optional suffix added.
+** ^If a suffix is added to the zFilename parameter, it will
+** consist of a single "-" character followed by no more than
+** 11 alphanumeric and/or "-" characters.
+** ^SQLite further guarantees that
+** the string will be valid and unchanged until xClose() is
+** called. Because of the previous sentence,
+** the [sqlite3_file] can safely store a pointer to the
+** filename if it needs to remember the filename for some reason.
+** If the zFilename parameter to xOpen is a NULL pointer then xOpen
+** must invent its own temporary name for the file.  ^Whenever the 
+** xFilename parameter is NULL it will also be the case that the
+** flags parameter will include [SQLITE_OPEN_DELETEONCLOSE].
+**
+** The flags argument to xOpen() includes all bits set in
+** the flags argument to [sqlite3_open_v2()].  Or if [sqlite3_open()]
+** or [sqlite3_open16()] is used, then flags includes at least
+** [SQLITE_OPEN_READWRITE] | [SQLITE_OPEN_CREATE]. 
+** If xOpen() opens a file read-only then it sets *pOutFlags to
+** include [SQLITE_OPEN_READONLY].  Other bits in *pOutFlags may be set.
+**
+** ^(SQLite will also add one of the following flags to the xOpen()
+** call, depending on the object being opened:
+**
+** <ul>
+** <li>  [SQLITE_OPEN_MAIN_DB]
+** <li>  [SQLITE_OPEN_MAIN_JOURNAL]
+** <li>  [SQLITE_OPEN_TEMP_DB]
+** <li>  [SQLITE_OPEN_TEMP_JOURNAL]
+** <li>  [SQLITE_OPEN_TRANSIENT_DB]
+** <li>  [SQLITE_OPEN_SUBJOURNAL]
+** <li>  [SQLITE_OPEN_MASTER_JOURNAL]
+** <li>  [SQLITE_OPEN_WAL]
+** </ul>)^
+**
+** The file I/O implementation can use the object type flags to
+** change the way it deals with files.  For example, an application
+** that does not care about crash recovery or rollback might make
+** the open of a journal file a no-op.  Writes to this journal would
+** also be no-ops, and any attempt to read the journal would return
+** SQLITE_IOERR.  Or the implementation might recognize that a database
+** file will be doing page-aligned sector reads and writes in a random
+** order and set up its I/O subsystem accordingly.
+**
+** SQLite might also add one of the following flags to the xOpen method:
+**
+** <ul>
+** <li> [SQLITE_OPEN_DELETEONCLOSE]
+** <li> [SQLITE_OPEN_EXCLUSIVE]
+** </ul>
+**
+** The [SQLITE_OPEN_DELETEONCLOSE] flag means the file should be
+** deleted when it is closed.  ^The [SQLITE_OPEN_DELETEONCLOSE]
+** will be set for TEMP databases and their journals, transient
+** databases, and subjournals.
+**
+** ^The [SQLITE_OPEN_EXCLUSIVE] flag is always used in conjunction
+** with the [SQLITE_OPEN_CREATE] flag, which are both directly
+** analogous to the O_EXCL and O_CREAT flags of the POSIX open()
+** API.  The SQLITE_OPEN_EXCLUSIVE flag, when paired with the 
+** SQLITE_OPEN_CREATE, is used to indicate that file should always
+** be created, and that it is an error if it already exists.
+** It is <i>not</i> used to indicate the file should be opened 
+** for exclusive access.
+**
+** ^At least szOsFile bytes of memory are allocated by SQLite
+** to hold the [sqlite3_file] structure passed as the third
+** argument to xOpen.  The xOpen method does not have to
+** allocate the structure; it should just fill it in.  Note that
+** the xOpen method must set the sqlite3_file.pMethods to either
+** a valid [sqlite3_io_methods] object or to NULL.  xOpen must do
+** this even if the open fails.  SQLite expects that the sqlite3_file.pMethods
+** element will be valid after xOpen returns regardless of the success
+** or failure of the xOpen call.
+**
+** [[sqlite3_vfs.xAccess]]
+** ^The flags argument to xAccess() may be [SQLITE_ACCESS_EXISTS]
+** to test for the existence of a file, or [SQLITE_ACCESS_READWRITE] to
+** test whether a file is readable and writable, or [SQLITE_ACCESS_READ]
+** to test whether a file is at least readable.  The SQLITE_ACCESS_READ
+** flag is never actually used and is not implemented in the built-in
+** VFSes of SQLite.  The file is named by the second argument and can be a
+** directory. The xAccess method returns [SQLITE_OK] on success or some
+** non-zero error code if there is an I/O error or if the name of
+** the file given in the second argument is illegal.  If SQLITE_OK
+** is returned, then non-zero or zero is written into *pResOut to indicate
+** whether or not the file is accessible.  
+**
+** ^SQLite will always allocate at least mxPathname+1 bytes for the
+** output buffer xFullPathname.  The exact size of the output buffer
+** is also passed as a parameter to both  methods. If the output buffer
+** is not large enough, [SQLITE_CANTOPEN] should be returned. Since this is
+** handled as a fatal error by SQLite, vfs implementations should endeavor
+** to prevent this by setting mxPathname to a sufficiently large value.
+**
+** The xRandomness(), xSleep(), xCurrentTime(), and xCurrentTimeInt64()
+** interfaces are not strictly a part of the filesystem, but they are
+** included in the VFS structure for completeness.
+** The xRandomness() function attempts to return nBytes bytes
+** of good-quality randomness into zOut.  The return value is
+** the actual number of bytes of randomness obtained.
+** The xSleep() method causes the calling thread to sleep for at
+** least the number of microseconds given.  ^The xCurrentTime()
+** method returns a Julian Day Number for the current date and time as
+** a floating point value.
+** ^The xCurrentTimeInt64() method returns, as an integer, the Julian
+** Day Number multiplied by 86400000 (the number of milliseconds in 
+** a 24-hour day).  
+** ^SQLite will use the xCurrentTimeInt64() method to get the current
+** date and time if that method is available (if iVersion is 2 or 
+** greater and the function pointer is not NULL) and will fall back
+** to xCurrentTime() if xCurrentTimeInt64() is unavailable.
+**
+** ^The xSetSystemCall(), xGetSystemCall(), and xNestSystemCall() interfaces
+** are not used by the SQLite core.  These optional interfaces are provided
+** by some VFSes to facilitate testing of the VFS code. By overriding 
+** system calls with functions under its control, a test program can
+** simulate faults and error conditions that would otherwise be difficult
+** or impossible to induce.  The set of system calls that can be overridden
+** varies from one VFS to another, and from one version of the same VFS to the
+** next.  Applications that use these interfaces must be prepared for any
+** or all of these interfaces to be NULL or for their behavior to change
+** from one release to the next.  Applications must not attempt to access
+** any of these methods if the iVersion of the VFS is less than 3.

+** A call to sqlite3_initialize() is an "effective" call if it is

+** All other valid calls to sqlite3_shutdown() are harmless no-ops.)^
+**
+** The sqlite3_initialize() interface is threadsafe, but sqlite3_shutdown()
+** is not.  The sqlite3_shutdown() interface must only be called from a

+**
+** Among other things, ^sqlite3_initialize() will invoke

+** ^The sqlite3_initialize() routine returns [SQLITE_OK] on success.
+** ^If for some reason, sqlite3_initialize() is unable to initialize
+** the library (perhaps it is unable to allocate a needed resource such
+** as a mutex) it returns an [error code] other than [SQLITE_OK].
+**
+** ^The sqlite3_initialize() routine is called internally by many other

+** This object is used in only one place in the SQLite interface.
+** A pointer to an instance of this object is the argument to
+** [sqlite3_config()] when the configuration option is
+** [SQLITE_CONFIG_MALLOC] or [SQLITE_CONFIG_GETMALLOC].  
+** By creating an instance of this object
+** and passing it to [sqlite3_config]([SQLITE_CONFIG_MALLOC])
+** during configuration, an application can specify an alternative
+** memory allocation subsystem for SQLite to use for all of its
+** dynamic memory needs.
+**
+** Note that SQLite comes with several [built-in memory allocators]
+** that are perfectly adequate for the overwhelming majority of applications
+** and that this object is only useful to a tiny minority of applications
+** with specialized memory allocation requirements.  This object is
+** also used during testing of SQLite in order to specify an alternative
+** memory allocator that simulates memory out-of-memory conditions in
+** order to verify that SQLite recovers gracefully from such
+** conditions.
+**
+** The xMalloc, xRealloc, and xFree methods must work like the
+** malloc(), realloc() and free() functions from the standard C library.
+** ^SQLite guarantees that the second argument to
+** xRealloc is always a value returned by a prior call to xRoundup.
+**
+** xSize should return the allocated size of a memory allocation
+** previously obtained from xMalloc or xRealloc.  The allocated size
+** is always at least as big as the requested size but may be larger.
+**
+** The xRoundup method returns what would be the allocated size of
+** a memory allocation given a particular requested size.  Most memory
+** allocators round up memory allocations at least to the next multiple
+** of 8.  Some allocators round up to a larger multiple or to a power of 2.
+** Every memory allocation request coming in through [sqlite3_malloc()]
+** or [sqlite3_realloc()] first calls xRoundup.  If xRoundup returns 0, 
+** that causes the corresponding memory allocation to fail.
+**
+** The xInit method initializes the memory allocator.  For example,
+** it might allocate any required mutexes or initialize internal data
+** structures.  The xShutdown method is invoked (indirectly) by
+** [sqlite3_shutdown()] and should deallocate any resources acquired
+** by xInit.  The pAppData pointer is used as the only parameter to
+** xInit and xShutdown.
+**
+** SQLite holds the [SQLITE_MUTEX_STATIC_MASTER] mutex when it invokes
+** the xInit method, so the xInit method need not be threadsafe.  The
+** xShutdown method is only called from [sqlite3_shutdown()] so it does
+** not need to be threadsafe either.  For all other methods, SQLite
+** holds the [SQLITE_MUTEX_STATIC_MEM] mutex as long as the
+** [SQLITE_CONFIG_MEMSTATUS] configuration option is turned on (which
+** it is by default) and so the methods are automatically serialized.
+** However, if [SQLITE_CONFIG_MEMSTATUS] is disabled, then the other

+** serialization.

+**
+** Things are more complicated if the sqlite3_changes() function is

+** by the first INSERT, UPDATE or DELETE statement within a trigger, it 
+** returns the value as set when the calling statement began executing.

+** CAPI3REF: Convenience Routines For Running Queries
+** METHOD: sqlite3
+**
+** This is a legacy interface that is preserved for backwards compatibility.
+** Use of this interface is not recommended.
+**
+** Definition: A <b>result table</b> is memory data structure created by the
+** [sqlite3_get_table()] interface.  A result table records the
+** complete query results from one or more queries.
+**
+** The table conceptually has a number of rows and columns.  But
+** these numbers are not part of the result table itself.  These
+** numbers are obtained separately.  Let N be the number of rows
+** and M be the number of columns.
+**
+** A result table is an array of pointers to zero-terminated UTF-8 strings.
+** There are (N+1)*M elements in the array.  The first M pointers point
+** to zero-terminated strings that  contain the names of the columns.
+** The remaining entries all point to query results.  NULL values result
+** in NULL pointers.  All other values are in their UTF-8 zero-terminated
+** string representation as returned by [sqlite3_column_text()].
+**
+** A result table might consist of one or more memory allocations.
+** It is not safe to pass a result table directly to [sqlite3_free()].
+** A result table should be deallocated using [sqlite3_free_table()].
+**
+** ^(As an example of the result table format, suppose a query result
+** is as follows:
+**
+** <blockquote><pre>
+**        Name        | Age
+**        -----------------------
+**        Alice       | 43
+**        Bob         | 28
+**        Cindy       | 21
+** </pre></blockquote>
+**
+** There are two columns (M==2) and three rows (N==3).  Thus the
+** result table has 8 entries.  Suppose the result table is stored
+** in an array named azResult.  Then azResult holds this content:
+**
+** <blockquote><pre>
+**        azResult&#91;0] = "Name";
+**        azResult&#91;1] = "Age";
+**        azResult&#91;2] = "Alice";
+**        azResult&#91;3] = "43";
+**        azResult&#91;4] = "Bob";
+**        azResult&#91;5] = "28";
+**        azResult&#91;6] = "Cindy";
+**        azResult&#91;7] = "21";
+** </pre></blockquote>)^
+**
+** ^The sqlite3_get_table() function evaluates one or more
+** semicolon-separated SQL statements in the zero-terminated UTF-8
+** string of its 2nd parameter and returns a result table to the
+** pointer given in its 3rd parameter.
+**

+** [sqlite3_malloc()] happens within sqlite3_get_table(), the calling
+** function must not try to call [sqlite3_free()] directly.  Only
+** [sqlite3_free_table()] is able to release the memory properly and safely.
+**
+** The sqlite3_get_table() interface is implemented as a wrapper around
+** [sqlite3_exec()].  The sqlite3_get_table() routine does not have access
+** to any internal data structures of SQLite.  It uses only the public

+**
+** ^The first parameter to the authorizer callback is a copy of the third

+** to the callback is an integer [SQLITE_COPY | action code] that specifies
+** the particular action to be authorized. ^The third through sixth parameters
+** to the callback are either NULL pointers or zero-terminated strings
+** that contain additional details about the action to be authorized.
+** Applications must always be prepared to encounter a NULL pointer in any
+** of the third through the sixth parameters of the authorization callback.
+**
+** ^If the action code is [SQLITE_READ]

+** disallows everything except [SELECT] statements.
+**
+** Applications that need to process SQL from untrusted sources

+** [[URI filenames in sqlite3_open()]] <h3>URI Filenames</h3>
+**
+** ^If [URI filename] interpretation is enabled, and the filename argument
+** begins with "file:", then the filename is interpreted as a URI. ^URI
+** filename interpretation is enabled if the [SQLITE_OPEN_URI] flag is
+** set in the third argument to sqlite3_open_v2(), or if it has
+** been enabled globally using the [SQLITE_CONFIG_URI] option with the
+** [sqlite3_config()] method or by the [SQLITE_USE_URI] compile-time option.
+** URI filename interpretation is turned off
+** by default, but future releases of SQLite might enable URI filename
+** interpretation by default.  See "[URI filenames]" for additional
+** information.
+**
+** URI filenames are parsed according to RFC 3986. ^If the URI contains an
+** authority, then it must be either an empty string or the string 
+** "localhost". ^If the authority is not an empty string or "localhost", an 
+** error is returned to the caller. ^The fragment component of a URI, if 
+** present, is ignored.
+**
+** ^SQLite uses the path component of the URI as the name of the disk file
+** which contains the database. ^If the path begins with a '/' character, 
+** then it is interpreted as an absolute path. ^If the path does not begin 
+** with a '/' (meaning that the authority section is omitted from the URI)
+** then the path is interpreted as a relative path. 
+** ^(On windows, the first component of an absolute path 
+** is a drive specification (e.g. "C:").)^
+**
+** [[core URI query parameters]]
+** The query component of a URI may contain parameters that are interpreted
+** either by SQLite itself, or by a [VFS | custom VFS implementation].
+** SQLite and its built-in [VFSes] interpret the
+** following query parameters:
+**
+** <ul>
+**   <li> <b>vfs</b>: ^The "vfs" parameter may be used to specify the name of
+**     a VFS object that provides the operating system interface that should
+**     be used to access the database file on disk. ^If this option is set to
+**     an empty string the default VFS object is used. ^Specifying an unknown
+**     VFS is an error. ^If sqlite3_open_v2() is used and the vfs option is
+**     present, then the VFS specified by the option takes precedence over
+**     the value passed as the fourth parameter to sqlite3_open_v2().
+**
+**   <li> <b>mode</b>: ^(The mode parameter may be set to either "ro", "rw",
+**     "rwc", or "memory". Attempting to set it to any other value is
+**     an error)^. 
+**     ^If "ro" is specified, then the database is opened for read-only 
+**     access, just as if the [SQLITE_OPEN_READONLY] flag had been set in the 
+**     third argument to sqlite3_open_v2(). ^If the mode option is set to 
+**     "rw", then the database is opened for read-write (but not create) 
+**     access, as if SQLITE_OPEN_READWRITE (but not SQLITE_OPEN_CREATE) had 
+**     been set. ^Value "rwc" is equivalent to setting both 
+**     SQLITE_OPEN_READWRITE and SQLITE_OPEN_CREATE.  ^If the mode option is
+**     set to "memory" then a pure [in-memory database] that never reads
+**     or writes from disk is used. ^It is an error to specify a value for
+**     the mode parameter that is less restrictive than that specified by
+**     the flags passed in the third parameter to sqlite3_open_v2().
+**
+**   <li> <b>cache</b>: ^The cache parameter may be set to either "shared" or
+**     "private". ^Setting it to "shared" is equivalent to setting the
+**     SQLITE_OPEN_SHAREDCACHE bit in the flags argument passed to
+**     sqlite3_open_v2(). ^Setting the cache parameter to "private" is 
+**     equivalent to setting the SQLITE_OPEN_PRIVATECACHE bit.
+**     ^If sqlite3_open_v2() is used and the "cache" parameter is present in
+**     a URI filename, its value overrides any behavior requested by setting
+**     SQLITE_OPEN_PRIVATECACHE or SQLITE_OPEN_SHAREDCACHE flag.
+**
+**  <li> <b>psow</b>: ^The psow parameter indicates whether or not the
+**     [powersafe overwrite] property does or does not apply to the
+**     storage media on which the database file resides.
+**
+**  <li> <b>nolock</b>: ^The nolock parameter is a boolean query parameter
+**     which if set disables file locking in rollback journal modes.  This
+**     is useful for accessing a database on a filesystem that does not
+**     support locking.  Caution:  Database corruption might result if two
+**     or more processes write to the same database and any one of those
+**     processes uses nolock=1.
+**
+**  <li> <b>immutable</b>: ^The immutable parameter is a boolean query
+**     parameter that indicates that the database file is stored on
+**     read-only media.  ^When immutable is set, SQLite assumes that the
+**     database file cannot be changed, even by a process with higher
+**     privilege, and so the database is opened read-only and all locking
+**     and change detection is disabled.  Caution: Setting the immutable
+**     property on a database file that does in fact change can result
+**     in incorrect query results and/or [SQLITE_CORRUPT] errors.
+**     See also: [SQLITE_IOCAP_IMMUTABLE].
+**       
+** </ul>
+**
+** ^Specifying an unknown parameter in the query component of a URI is not an
+** error.  Future versions of SQLite might understand additional query
+** parameters.  See "[query parameters with special meaning to SQLite]" for
+** additional information.

+** CAPI3REF: Obtain Values For URI Parameters
+**
+** These are utility routines, useful to [VFS|custom VFS implementations],
+** that check if a database file was a URI that contained a specific query 
+** parameter, and if so obtains the value of that query parameter.
+**
+** The first parameter to these interfaces (hereafter referred to
+** as F) must be one of:
+** <ul>
+** <li> A database filename pointer created by the SQLite core and
+** passed into the xOpen() method of a VFS implemention, or
+** <li> A filename obtained from [sqlite3_db_filename()], or
+** <li> A new filename constructed using [sqlite3_create_filename()].
+** </ul>
+** If the F parameter is not one of the above, then the behavior is
+** undefined and probably undesirable.  Older versions of SQLite were
+** more tolerant of invalid F parameters than newer versions.
+**
+** If F is a suitable filename (as described in the previous paragraph)
+** and if P is the name of the query parameter, then
+** sqlite3_uri_parameter(F,P) returns the value of the P
+** parameter if it exists or a NULL pointer if P does not appear as a 
+** query parameter on F.  If P is a query parameter of F and it
+** has no explicit value, then sqlite3_uri_parameter(F,P) returns
+** a pointer to an empty string.
+**
+** The sqlite3_uri_boolean(F,P,B) routine assumes that P is a boolean
+** parameter and returns true (1) or false (0) according to the value
+** of P.  The sqlite3_uri_boolean(F,P,B) routine returns true (1) if the
+** value of query parameter P is one of "yes", "true", or "on" in any
+** case or if the value begins with a non-zero number.  The 
+** sqlite3_uri_boolean(F,P,B) routines returns false (0) if the value of
+** query parameter P is one of "no", "false", or "off" in any case or
+** if the value begins with a numeric zero.  If P is not a query
+** parameter on F or if the value of P does not match any of the
+** above, then sqlite3_uri_boolean(F,P,B) returns (B!=0).
+**
+** The sqlite3_uri_int64(F,P,D) routine converts the value of P into a
+** 64-bit signed integer and returns that integer, or D if P does not
+** exist.  If the value of P is something other than an integer, then
+** zero is returned.
+**
+** The sqlite3_uri_key(F,N) returns a pointer to the name (not
+** the value) of the N-th query parameter for filename F, or a NULL
+** pointer if N is less than zero or greater than the number of query
+** parameters minus 1.  The N value is zero-based so N should be 0 to obtain
+** the name of the first query parameter, 1 for the second parameter, and
+** so forth.
+** 
+** If F is a NULL pointer, then sqlite3_uri_parameter(F,P) returns NULL and
+** sqlite3_uri_boolean(F,P,B) returns B.  If F is not a NULL pointer and
+** is not a database file pathname pointer that the SQLite core passed
+** into the xOpen VFS method, then the behavior of this routine is undefined
+** and probably undesirable.
+**
+** Beginning with SQLite [version 3.31.0] ([dateof:3.31.0]) the input F
+** parameter can also be the name of a rollback journal file or WAL file
+** in addition to the main database file.  Prior to version 3.31.0, these
+** routines would only work if F was the name of the main database file.
+** When the F parameter is the name of the rollback journal or WAL file,

+** CAPI3REF: Compiling An SQL Statement
+** KEYWORDS: {SQL statement compiler}
+** METHOD: sqlite3
+** CONSTRUCTOR: sqlite3_stmt
+**
+** To execute an SQL statement, it must first be compiled into a byte-code
+** program using one of these routines.  Or, in other words, these routines
+** are constructors for the [prepared statement] object.
+**
+** The preferred routine to use is [sqlite3_prepare_v2()].  The
+** [sqlite3_prepare()] interface is legacy and should be avoided.
+** [sqlite3_prepare_v3()] has an extra "prepFlags" option that is used
+** for special purposes.
+**
+** The use of the UTF-8 interfaces is preferred, as SQLite currently
+** does all parsing using UTF-8.  The UTF-16 interfaces are provided
+** as a convenience.  The UTF-16 interfaces work by converting the
+** input text into UTF-8, then invoking the corresponding UTF-8 interface.
+**
+** The first argument, "db", is a [database connection] obtained from a
+** prior successful call to [sqlite3_open()], [sqlite3_open_v2()] or
+** [sqlite3_open16()].  The database connection must not have been closed.
+**
+** The second argument, "zSql", is the statement to be compiled, encoded
+** as either UTF-8 or UTF-16.  The sqlite3_prepare(), sqlite3_prepare_v2(),
+** and sqlite3_prepare_v3()
+** interfaces use UTF-8, and sqlite3_prepare16(), sqlite3_prepare16_v2(),
+** and sqlite3_prepare16_v3() use UTF-16.
+**
+** ^If the nByte argument is negative, then zSql is read up to the
+** first zero terminator. ^If nByte is positive, then it is the
+** number of bytes read from zSql.  ^If nByte is zero, then no prepared
+** statement is generated.
+** If the caller knows that the supplied string is nul-terminated, then
+** there is a small performance advantage to passing an nByte parameter that
+** is the number of bytes in the input string <i>including</i>
+** the nul-terminator.
+**
+** ^If pzTail is not NULL then *pzTail is made to point to the first byte
+** past the end of the first SQL statement in zSql.  These routines only
+** compile the first statement in zSql, so *pzTail is left pointing to
+** what remains uncompiled.
+**
+** ^*ppStmt is left pointing to a compiled [prepared statement] that can be
+** executed using [sqlite3_step()].  ^If there is an error, *ppStmt is set
+** to NULL.  ^If the input text contains no SQL (if the input is an empty
+** string or a comment) then *ppStmt is set to NULL.
+** The calling procedure is responsible for deleting the compiled
+** SQL statement using [sqlite3_finalize()] after it has finished with it.
+** ppStmt may not be NULL.
+**
+** ^On success, the sqlite3_prepare() family of routines return [SQLITE_OK];
+** otherwise an [error code] is returned.
+**
+** The sqlite3_prepare_v2(), sqlite3_prepare_v3(), sqlite3_prepare16_v2(),
+** and sqlite3_prepare16_v3() interfaces are recommended for all new programs.
+** The older interfaces (sqlite3_prepare() and sqlite3_prepare16())
+** are retained for backwards compatibility, but their use is discouraged.
+** ^In the "vX" interfaces, the prepared statement
+** that is returned (the [sqlite3_stmt] object) contains a copy of the
+** original SQL text. This causes the [sqlite3_step()] interface to
+** behave differently in three ways:
+**
+** <ol>
+** <li>
+** ^If the database schema changes, instead of returning [SQLITE_SCHEMA] as it
+** always used to do, [sqlite3_step()] will automatically recompile the SQL
+** statement and try to run it again. As many as [SQLITE_MAX_SCHEMA_RETRY]
+** retries will occur before sqlite3_step() gives up and returns an error.
+** </li>

+** must be called one or more times to evaluate the statement.
+**
+** The details of the behavior of the sqlite3_step() interface depend

+** [sqlite3_prepare_v3()], [sqlite3_prepare_v2()], [sqlite3_prepare16_v3()],
+** [sqlite3_prepare16_v2()] or the older legacy
+** interfaces [sqlite3_prepare()] and [sqlite3_prepare16()].  The use of the
+** new "vX" interface is recommended for new applications but the legacy
+** interface will continue to be supported.
+**
+** ^In the legacy interface, the return value will be either [SQLITE_BUSY],
+** [SQLITE_DONE], [SQLITE_ROW], [SQLITE_ERROR], or [SQLITE_MISUSE].
+** ^With the "v2" interface, any of the other [result codes] or
+** [extended result codes] might be returned as well.
+**
+** ^[SQLITE_BUSY] means that the database engine was unable to acquire the
+** database locks it needs to do its job.  ^If the statement is a [COMMIT]
+** or occurs outside of an explicit transaction, then you can retry the
+** statement.  If the statement is not a [COMMIT] and occurs within an
+** explicit transaction then you should rollback the transaction before
+** continuing.
+**
+** ^[SQLITE_DONE] means that the statement has finished executing
+** successfully.  sqlite3_step() should not be called again on this virtual
+** machine without first calling [sqlite3_reset()] to reset the virtual
+** machine back to its initial state.
+**
+** ^If the SQL statement being executed returns any data, then [SQLITE_ROW]
+** is returned each time a new row of data is ready for processing by the
+** caller. The values may be accessed using the [column access functions].
+** sqlite3_step() is called again to retrieve the next row of data.
+**
+** ^[SQLITE_ERROR] means that a run-time error (such as a constraint
+** violation) has occurred.  sqlite3_step() should not be called again on
+** the VM. More information may be found by calling [sqlite3_errmsg()].
+** ^With the legacy interface, a more specific error code (for example,
+** [SQLITE_INTERRUPT], [SQLITE_SCHEMA], [SQLITE_CORRUPT], and so forth)
+** can be obtained by calling [sqlite3_reset()] on the
+** [prepared statement].  ^In the "v2" interface,
+** the more specific error code is returned directly by sqlite3_step().
+**
+** [SQLITE_MISUSE] means that the this routine was called inappropriately.
+** Perhaps it was called on a [prepared statement] that has
+** already been [sqlite3_finalize | finalized] or on one that had
+** previously returned [SQLITE_ERROR] or [SQLITE_DONE].  Or it could
+** be the case that the same database connection is being used by two or
+** more threads at the same moment in time.
+**
+** For all versions of SQLite up to and including 3.6.23.1, a call to
+** [sqlite3_reset()] was required after sqlite3_step() returned anything
+** other than [SQLITE_ROW] before any subsequent invocation of
+** sqlite3_step().  Failure to reset the prepared statement using 
+** [sqlite3_reset()] would result in an [SQLITE_MISUSE] return from
+** sqlite3_step().  But after [version 3.6.23.1] ([dateof:3.6.23.1],
+** sqlite3_step() began
+** calling [sqlite3_reset()] automatically in this circumstance rather
+** than returning [SQLITE_MISUSE].  This is not considered a compatibility
+** break because any application that ever receives an SQLITE_MISUSE error
+** is broken by definition.  The [SQLITE_OMIT_AUTORESET] compile-time option
+** can be used to restore the legacy behavior.
+**
+** <b>Goofy Interface Alert:</b> In the legacy interface, the sqlite3_step()
+** API always returns a generic error code, [SQLITE_ERROR], following any
+** error other than [SQLITE_BUSY] and [SQLITE_MISUSE].  You must call
+** [sqlite3_reset()] or [sqlite3_finalize()] in order to find one of the
+** specific [error codes] that better describes the error.

+**
+** ^These routines return information about a single column of the current
+** result row of a query.  ^In every case the first argument is a pointer
+** to the [prepared statement] that is being evaluated (the [sqlite3_stmt*]
+** that was returned from [sqlite3_prepare_v2()] or one of its variants)
+** and the second argument is the index of the column for which information
+** should be returned. ^The leftmost column of the result set has the index 0.
+** ^The number of columns in the result can be determined using
+** [sqlite3_column_count()].
+**
+** If the SQL statement does not currently point to a valid row, or if the
+** column index is out of range, the result is undefined.
+** These routines may only be called when the most recent call to
+** [sqlite3_step()] has returned [SQLITE_ROW] and neither
+** [sqlite3_reset()] nor [sqlite3_finalize()] have been called subsequently.
+** If any of these routines are called after [sqlite3_reset()] or
+** [sqlite3_finalize()] or after [sqlite3_step()] has returned
+** something other than [SQLITE_ROW], the results are undefined.
+** If [sqlite3_step()] or [sqlite3_reset()] or [sqlite3_finalize()]
+** are called from a different thread while any of these routines
+** are pending, then the results are undefined.
+**
+** The first six interfaces (_blob, _double, _int, _int64, _text, and _text16)
+** each return the value of a result column in a specific data format.  If
+** the result column is not initially in the requested format (for example,
+** if the query returns an integer but the sqlite3_column_text() interface
+** is used to extract the value) then an automatic type conversion is performed.
+**
+** ^The sqlite3_column_type() routine returns the
+** [SQLITE_INTEGER | datatype code] for the initial data type
+** of the result column.  ^The returned value is one of [SQLITE_INTEGER],
+** [SQLITE_FLOAT], [SQLITE_TEXT], [SQLITE_BLOB], or [SQLITE_NULL].
+** The return value of sqlite3_column_type() can be used to decide which
+** of the first six interface should be used to extract the column value.
+** The value returned by sqlite3_column_type() is only meaningful if no
+** automatic type conversions have occurred for the value in question.  
+** After a type conversion, the result of calling sqlite3_column_type()
+** is undefined, though harmless.  Future
+** versions of SQLite may change the behavior of sqlite3_column_type()
+** following a type conversion.
+**
+** If the result is a BLOB or a TEXT string, then the sqlite3_column_bytes()
+** or sqlite3_column_bytes16() interfaces can be used to determine the size
+** of that BLOB or string.
+**
+** ^If the result is a BLOB or UTF-8 string then the sqlite3_column_bytes()
+** routine returns the number of bytes in that BLOB or string.
+** ^If the result is a UTF-16 string, then sqlite3_column_bytes() converts
+** the string to UTF-8 and then returns the number of bytes.
+** ^If the result is a numeric value then sqlite3_column_bytes() uses
+** [sqlite3_snprintf()] to convert that value to a UTF-8 string and returns
+** the number of bytes in that string.
+** ^If the result is NULL, then sqlite3_column_bytes() returns zero.
+**
+** ^If the result is a BLOB or UTF-16 string then the sqlite3_column_bytes16()
+** routine returns the number of bytes in that BLOB or string.
+** ^If the result is a UTF-8 string, then sqlite3_column_bytes16() converts
+** the string to UTF-16 and then returns the number of bytes.
+** ^If the result is a numeric value then sqlite3_column_bytes16() uses
+** [sqlite3_snprintf()] to convert that value to a UTF-16 string and returns
+** the number of bytes in that string.
+** ^If the result is NULL, then sqlite3_column_bytes16() returns zero.
+**
+** ^The values returned by [sqlite3_column_bytes()] and 
+** [sqlite3_column_bytes16()] do not include the zero terminators at the end
+** of the string.  ^For clarity: the values returned by
+** [sqlite3_column_bytes()] and [sqlite3_column_bytes16()] are the number of
+** bytes in the string, not the number of characters.
+**
+** ^Strings returned by sqlite3_column_text() and sqlite3_column_text16(),
+** even empty strings, are always zero-terminated.  ^The return
+** value from sqlite3_column_blob() for a zero-length BLOB is a NULL pointer.
+**
+** <b>Warning:</b> ^The object returned by [sqlite3_column_value()] is an
+** [unprotected sqlite3_value] object.  In a multithreaded environment,
+** an unprotected sqlite3_value object may only be used safely with
+** [sqlite3_bind_value()] and [sqlite3_result_value()].
+** If the [unprotected sqlite3_value] object returned by
+** [sqlite3_column_value()] is used in any other way, including calls
+** to routines like [sqlite3_value_int()], [sqlite3_value_text()],
+** or [sqlite3_value_bytes()], the behavior is not threadsafe.
+** Hence, the sqlite3_column_value() interface
+** is normally only useful within the implementation of 
+** [application-defined SQL functions] or [virtual tables], not within
+** top-level application code.
+**
+** The these routines may attempt to convert the datatype of the result.
+** ^For example, if the internal representation is FLOAT and a text result
+** is requested, [sqlite3_snprintf()] is used internally to perform the
+** conversion automatically.  ^(The following table details the conversions
+** that are applied:
+**
+** <blockquote>
+** <table border="1">
+** <tr><th> Internal<br>Type <th> Requested<br>Type <th>  Conversion
+**
+** <tr><td>  NULL    <td> INTEGER   <td> Result is 0
+** <tr><td>  NULL    <td>  FLOAT    <td> Result is 0.0
+** <tr><td>  NULL    <td>   TEXT    <td> Result is a NULL pointer
+** <tr><td>  NULL    <td>   BLOB    <td> Result is a NULL pointer
+** <tr><td> INTEGER  <td>  FLOAT    <td> Convert from integer to float
+** <tr><td> INTEGER  <td>   TEXT    <td> ASCII rendering of the integer
+** <tr><td> INTEGER  <td>   BLOB    <td> Same as INTEGER->TEXT
+** <tr><td>  FLOAT   <td> INTEGER   <td> [CAST] to INTEGER

+** </blockquote>)^
+**
+** Note that when type conversions occur, pointers returned by prior
+** calls to sqlite3_column_blob(), sqlite3_column_text(), and/or
+** sqlite3_column_text16() may be invalidated.
+** Type conversions and pointer invalidations might occur
+** in the following cases:
+**
+** <ul>
+** <li> The initial content is a BLOB and sqlite3_column_text() or
+**      sqlite3_column_text16() is called.  A zero-terminator might
+**      need to be added to the string.</li>
+** <li> The initial content is UTF-8 text and sqlite3_column_bytes16() or
+**      sqlite3_column_text16() is called.  The content must be converted
+**      to UTF-16.</li>
+** <li> The initial content is UTF-16 text and sqlite3_column_bytes() or
+**      sqlite3_column_text() is called.  The content must be converted
+**      to UTF-8.</li>
+** </ul>
+**
+** ^Conversions between UTF-16be and UTF-16le are always done in place and do
+** not invalidate a prior pointer, though of course the content of the buffer
+** that the prior pointer references will have been modified.  Other kinds
+** of conversion are done in place when it is possible, but sometimes they
+** are not possible and in those cases prior pointers are invalidated.
+**
+** The safest policy is to invoke these routines
+** in one of the following ways:
+**
+** <ul>
+**  <li>sqlite3_column_text() followed by sqlite3_column_bytes()</li>
+**  <li>sqlite3_column_blob() followed by sqlite3_column_bytes()</li>
+**  <li>sqlite3_column_text16() followed by sqlite3_column_bytes16()</li>
+** </ul>
+**
+** In other words, you should call sqlite3_column_text(),
+** sqlite3_column_blob(), or sqlite3_column_text16() first to force the result
+** into the desired format, then invoke sqlite3_column_bytes() or
+** sqlite3_column_bytes16() to find the size of the result.  Do not mix calls
+** to sqlite3_column_text() or sqlite3_column_blob() with calls to
+** sqlite3_column_bytes16(), and do not mix calls to sqlite3_column_text16()
+** with calls to sqlite3_column_bytes().
+**
+** ^The pointers returned are valid until a type conversion occurs as
+** described above, or until [sqlite3_step()] or [sqlite3_reset()] or
+** [sqlite3_finalize()] is called.  ^The memory space used to hold strings
+** and BLOBs is freed automatically.  Do not pass the pointers returned
+** from [sqlite3_column_blob()], [sqlite3_column_text()], etc. into
+** [sqlite3_free()].
+**
+** As long as the input parameters are correct, these routines will only
+** fail if an out-of-memory error occurs during a format conversion.
+** Only the following subset of interfaces are subject to out-of-memory
+** errors:
+**
+** <ul>
+** <li> sqlite3_column_blob()
+** <li> sqlite3_column_text()
+** <li> sqlite3_column_text16()
+** <li> sqlite3_column_bytes()
+** <li> sqlite3_column_bytes16()
+** </ul>
+**
+** If an out-of-memory error occurs, then the return value from these
+** routines is the same as if the column had contained an SQL NULL value.
+** Valid SQL NULL returns can be distinguished from out-of-memory errors
+** by invoking the [sqlite3_errcode()] immediately after the suspect
+** return value is obtained and before any
+** other SQLite interface is called on the same [database connection].

+** function is to be added.  ^If an application uses more than one database
+** connection then application-defined SQL functions must be added
+** to each database connection separately.
+**
+** ^The second parameter is the name of the SQL function to be created or
+** redefined.  ^The length of the name is limited to 255 bytes in a UTF-8
+** representation, exclusive of the zero-terminator.  ^Note that the name
+** length limit is in UTF-8 bytes, not characters nor UTF-16 bytes.  
+** ^Any attempt to create a function with a longer name
+** will result in [SQLITE_MISUSE] being returned.
+**
+** ^The third parameter (nArg)
+** is the number of arguments that the SQL function or
+** aggregate takes. ^If this parameter is -1, then the SQL function or
+** aggregate may take any number of arguments between 0 and the limit
+** set by [sqlite3_limit]([SQLITE_LIMIT_FUNCTION_ARG]).  If the third
+** parameter is less than -1 or greater than 127 then the behavior is
+** undefined.
+**
+** ^The fourth parameter, eTextRep, specifies what
+** [SQLITE_UTF8 | text encoding] this SQL function prefers for
+** its parameters.  The application should set this parameter to
+** [SQLITE_UTF16LE] if the function implementation invokes 
+** [sqlite3_value_text16le()] on an input, or [SQLITE_UTF16BE] if the
+** implementation invokes [sqlite3_value_text16be()] on an input, or
+** [SQLITE_UTF16] if [sqlite3_value_text16()] is used, or [SQLITE_UTF8]
+** otherwise.  ^The same SQL function may be registered multiple times using
+** different preferred text encodings, with different implementations for
+** each encoding.
+** ^When multiple implementations of the same function are available, SQLite
+** will pick the one that involves the least amount of data conversion.
+**
+** ^The fourth parameter may optionally be ORed with [SQLITE_DETERMINISTIC]
+** to signal that the function will always return the same result given
+** the same inputs within a single SQL statement.  Most SQL functions are
+** deterministic.  The built-in [random()] SQL function is an example of a
+** function that is not deterministic.  The SQLite query planner is able to
+** perform additional optimizations on deterministic functions, so use
+** of the [SQLITE_DETERMINISTIC] flag is recommended where possible.
+**
+** ^The fourth parameter may also optionally include the [SQLITE_DIRECTONLY]
+** flag, which if present prevents the function from being invoked from
+** within VIEWs, TRIGGERs, CHECK constraints, generated column expressions,
+** index expressions, or the WHERE clause of partial indexes.
+**
+** <span style="background-color:#ffff90;">
+** For best security, the [SQLITE_DIRECTONLY] flag is recommended for
+** all application-defined SQL functions that do not need to be
+** used inside of triggers, view, CHECK constraints, or other elements of
+** the database schema.  This flags is especially recommended for SQL 
+** functions that have side effects or reveal internal application state.
+** Without this flag, an attacker might be able to modify the schema of
+** a database file to include invocations of the function with parameters
+** chosen by the attacker, which the application will then execute when
+** the database file is opened and read.
+** </span>
+**
+** ^(The fifth parameter is an arbitrary pointer.  The implementation of the
+** function can gain access to this pointer using [sqlite3_user_data()].)^
+**
+** ^The sixth, seventh and eighth parameters passed to the three
+** "sqlite3_create_function*" functions, xFunc, xStep and xFinal, are
+** pointers to C-language functions that implement the SQL function or
+** aggregate. ^A scalar SQL function requires an implementation of the xFunc
+** callback only; NULL pointers must be passed as the xStep and xFinal
+** parameters. ^An aggregate SQL function requires an implementation of xStep
+** and xFinal and NULL pointer must be passed for xFunc. ^To delete an existing
+** SQL function or aggregate, pass NULL pointers for all three function
+** callbacks.
+**
+** ^The sixth, seventh, eighth and ninth parameters (xStep, xFinal, xValue 
+** and xInverse) passed to sqlite3_create_window_function are pointers to
+** C-language callbacks that implement the new function. xStep and xFinal
+** must both be non-NULL. xValue and xInverse may either both be NULL, in
+** which case a regular aggregate function is created, or must both be 
+** non-NULL, in which case the new function may be used as either an aggregate
+** or aggregate window function. More details regarding the implementation
+** of aggregate window functions are 
+** [user-defined window functions|available here].
+**
+** ^(If the final parameter to sqlite3_create_function_v2() or
+** sqlite3_create_window_function() is not NULL, then it is destructor for
+** the application data pointer. The destructor is invoked when the function 
+** is deleted, either by being overloaded or when the database connection 
+** closes.)^ ^The destructor is also invoked if the call to 
+** sqlite3_create_function_v2() fails.  ^When the destructor callback is
+** invoked, it is passed a single argument which is a copy of the application
+** data pointer which was the fifth parameter to sqlite3_create_function_v2().
+**
+** ^It is permitted to register multiple implementations of the same
+** functions with the same name but with either differing numbers of
+** arguments or differing preferred text encodings.  ^SQLite will use
+** the implementation that most closely matches the way in which the
+** SQL function is used.  ^A function implementation with a non-negative
+** nArg parameter is a better match than a function implementation with
+** a negative nArg.  ^A function where the preferred text encoding
+** matches the database encoding is a better
+** match than a function where the encoding is different.  
+** ^A function where the encoding difference is between UTF16le and UTF16be
+** is a closer match than a function where the encoding difference is
+** between UTF8 and UTF16.
+**
+** ^Built-in functions may be overloaded by new application-defined functions.
+**
+** ^An application-defined function is permitted to call other
+** SQLite interfaces.  However, such calls must not
+** close the database connection nor finalize or reset the prepared
+** statement in which the function is running.

+**
+** <b>Details:</b>
+**
+** These routines extract type, size, and content information from
+** [protected sqlite3_value] objects.  Protected sqlite3_value objects
+** are used to pass parameter information into the functions that
+** implement [application-defined SQL functions] and [virtual tables].
+**
+** These routines work only with [protected sqlite3_value] objects.
+** Any attempt to use these routines on an [unprotected sqlite3_value]
+** is not threadsafe.
+**
+** ^These routines work just like the corresponding [column access functions]
+** except that these routines take a single [protected sqlite3_value] object
+** pointer instead of a [sqlite3_stmt*] pointer and an integer column number.
+**
+** ^The sqlite3_value_text16() interface extracts a UTF-16 string
+** in the native byte-order of the host machine.  ^The
+** sqlite3_value_text16be() and sqlite3_value_text16le() interfaces
+** extract UTF-16 strings as big-endian and little-endian respectively.
+**
+** ^If [sqlite3_value] object V was initialized 
+** using [sqlite3_bind_pointer(S,I,P,X,D)] or [sqlite3_result_pointer(C,P,X,D)]
+** and if X and Y are strings that compare equal according to strcmp(X,Y),
+** then sqlite3_value_pointer(V,Y) will return the pointer P.  ^Otherwise,
+** sqlite3_value_pointer(V,Y) returns a NULL. The sqlite3_bind_pointer() 
+** routine is part of the [pointer passing interface] added for SQLite 3.20.0.
+**
+** ^(The sqlite3_value_type(V) interface returns the
+** [SQLITE_INTEGER | datatype code] for the initial datatype of the
+** [sqlite3_value] object V. The returned value is one of [SQLITE_INTEGER],
+** [SQLITE_FLOAT], [SQLITE_TEXT], [SQLITE_BLOB], or [SQLITE_NULL].)^
+** Other interfaces might change the datatype for an sqlite3_value object.
+** For example, if the datatype is initially SQLITE_INTEGER and
+** sqlite3_value_text(V) is called to extract a text value for that
+** integer, then subsequent calls to sqlite3_value_type(V) might return
+** SQLITE_TEXT.  Whether or not a persistent internal datatype conversion
+** occurs is undefined and may change from one release of SQLite to the next.
+**
+** ^(The sqlite3_value_numeric_type() interface attempts to apply
+** numeric affinity to the value.  This means that an attempt is
+** made to convert the value to an integer or floating point.  If
+** such a conversion is possible without loss of information (in other
+** words, if the value is a string that looks like a number)
+** then the conversion is performed.  Otherwise no conversion occurs.
+** The [SQLITE_INTEGER | datatype] after conversion is returned.)^
+**
+** ^Within the [xUpdate] method of a [virtual table], the
+** sqlite3_value_nochange(X) interface returns true if and only if
+** the column corresponding to X is unchanged by the UPDATE operation
+** that the xUpdate method call was invoked to implement and if
+** and the prior [xColumn] method call that was invoked to extracted
+** the value for that column returned without setting a result (probably
+** because it queried [sqlite3_vtab_nochange()] and found that the column
+** was unchanging).  ^Within an [xUpdate] method, any value for which
+** sqlite3_value_nochange(X) is true will in all other respects appear
+** to be a NULL value.  If sqlite3_value_nochange(X) is invoked anywhere other
+** than within an [xUpdate] method call for an UPDATE statement, then
+** the return value is arbitrary and meaningless.
+**
+** ^The sqlite3_value_frombind(X) interface returns non-zero if the
+** value X originated from one of the [sqlite3_bind_int|sqlite3_bind()]
+** interfaces.  ^If X comes from an SQL literal value, or a table column,
+** or an expression, then sqlite3_value_frombind(X) returns zero.
+**
+** Please pay particular attention to the fact that the pointer returned
+** from [sqlite3_value_blob()], [sqlite3_value_text()], or
+** [sqlite3_value_text16()] can be invalidated by a subsequent call to
+** [sqlite3_value_bytes()], [sqlite3_value_bytes16()], [sqlite3_value_text()],
+** or [sqlite3_value_text16()].
+**
+** These routines must be called from the same thread as
+** the SQL function that supplied the [sqlite3_value*] parameters.
+**
+** As long as the input parameter is correct, these routines can only
+** fail if an out-of-memory error occurs during a format conversion.
+** Only the following subset of interfaces are subject to out-of-memory
+** errors:
+**
+** <ul>
+** <li> sqlite3_value_blob()
+** <li> sqlite3_value_text()
+** <li> sqlite3_value_text16()
+** <li> sqlite3_value_text16le()
+** <li> sqlite3_value_text16be()
+** <li> sqlite3_value_bytes()
+** <li> sqlite3_value_bytes16()
+** </ul>
+**
+** If an out-of-memory error occurs, then the return value from these
+** routines is the same as if the column had contained an SQL NULL value.
+** Valid SQL NULL returns can be distinguished from out-of-memory errors
+** by invoking the [sqlite3_errcode()] immediately after the suspect
+** return value is obtained and before any
+** other SQLite interface is called on the same [database connection].

+**
+** These routines are used by the xFunc or xFinal callbacks that
+** implement SQL functions and aggregates.  See
+** [sqlite3_create_function()] and [sqlite3_create_function16()]
+** for additional information.
+**
+** These functions work very much like the [parameter binding] family of
+** functions used to bind values to host parameters in prepared statements.
+** Refer to the [SQL parameter] documentation for additional information.
+**
+** ^The sqlite3_result_blob() interface sets the result from
+** an application-defined function to be the BLOB whose content is pointed
+** to by the second parameter and which is N bytes long where N is the
+** third parameter.
+**
+** ^The sqlite3_result_zeroblob(C,N) and sqlite3_result_zeroblob64(C,N)
+** interfaces set the result of the application-defined function to be
+** a BLOB containing all zero bytes and N bytes in size.
+**
+** ^The sqlite3_result_double() interface sets the result from
+** an application-defined function to be a floating point value specified
+** by its 2nd argument.
+**
+** ^The sqlite3_result_error() and sqlite3_result_error16() functions
+** cause the implemented SQL function to throw an exception.
+** ^SQLite uses the string pointed to by the
+** 2nd parameter of sqlite3_result_error() or sqlite3_result_error16()
+** as the text of an error message.  ^SQLite interprets the error
+** message string from sqlite3_result_error() as UTF-8. ^SQLite
+** interprets the string from sqlite3_result_error16() as UTF-16 using
+** the same [byte-order determination rules] as [sqlite3_bind_text16()].
+** ^If the third parameter to sqlite3_result_error()
+** or sqlite3_result_error16() is negative then SQLite takes as the error
+** message all text up through the first zero character.
+** ^If the third parameter to sqlite3_result_error() or
+** sqlite3_result_error16() is non-negative then SQLite takes that many
+** bytes (not characters) from the 2nd parameter as the error message.
+** ^The sqlite3_result_error() and sqlite3_result_error16()
+** routines make a private copy of the error message text before
+** they return.  Hence, the calling function can deallocate or
+** modify the text after they return without harm.
+** ^The sqlite3_result_error_code() function changes the error code
+** returned by SQLite as a result of an error in a function.  ^By default,
+** the error code is SQLITE_ERROR.  ^A subsequent call to sqlite3_result_error()
+** or sqlite3_result_error16() resets the error code to SQLITE_ERROR.
+**
+** ^The sqlite3_result_error_toobig() interface causes SQLite to throw an
+** error indicating that a string or BLOB is too long to represent.
+**
+** ^The sqlite3_result_error_nomem() interface causes SQLite to throw an
+** error indicating that a memory allocation failed.
+**
+** ^The sqlite3_result_int() interface sets the return value
+** of the application-defined function to be the 32-bit signed integer
+** value given in the 2nd argument.
+** ^The sqlite3_result_int64() interface sets the return value
+** of the application-defined function to be the 64-bit signed integer
+** value given in the 2nd argument.
+**
+** ^The sqlite3_result_null() interface sets the return value
+** of the application-defined function to be NULL.
+**
+** ^The sqlite3_result_text(), sqlite3_result_text16(),
+** sqlite3_result_text16le(), and sqlite3_result_text16be() interfaces
+** set the return value of the application-defined function to be
+** a text string which is represented as UTF-8, UTF-16 native byte order,
+** UTF-16 little endian, or UTF-16 big endian, respectively.
+** ^The sqlite3_result_text64() interface sets the return value of an
+** application-defined function to be a text string in an encoding
+** specified by the fifth (and last) parameter, which must be one
+** of [SQLITE_UTF8], [SQLITE_UTF16], [SQLITE_UTF16BE], or [SQLITE_UTF16LE].
+** ^SQLite takes the text result from the application from
+** the 2nd parameter of the sqlite3_result_text* interfaces.
+** ^If the 3rd parameter to the sqlite3_result_text* interfaces
+** is negative, then SQLite takes result text from the 2nd parameter
+** through the first zero character.
+** ^If the 3rd parameter to the sqlite3_result_text* interfaces
+** is non-negative, then as many bytes (not characters) of the text
+** pointed to by the 2nd parameter are taken as the application-defined
+** function result.  If the 3rd parameter is non-negative, then it
+** must be the byte offset into the string where the NUL terminator would
+** appear if the string where NUL terminated.  If any NUL characters occur
+** in the string at a byte offset that is less than the value of the 3rd
+** parameter, then the resulting string will contain embedded NULs and the
+** result of expressions operating on strings with embedded NULs is undefined.
+** ^If the 4th parameter to the sqlite3_result_text* interfaces
+** or sqlite3_result_blob is a non-NULL pointer, then SQLite calls that
+** function as the destructor on the text or BLOB result when it has
+** finished using that result.
+** ^If the 4th parameter to the sqlite3_result_text* interfaces or to
+** sqlite3_result_blob is the special constant SQLITE_STATIC, then SQLite
+** assumes that the text or BLOB result is in constant space and does not
+** copy the content of the parameter nor call a destructor on the content
+** when it has finished using that result.
+** ^If the 4th parameter to the sqlite3_result_text* interfaces
+** or sqlite3_result_blob is the special constant SQLITE_TRANSIENT
+** then SQLite makes a copy of the result into space obtained
+** from [sqlite3_malloc()] before it returns.
+**
+** ^For the sqlite3_result_text16(), sqlite3_result_text16le(), and
+** sqlite3_result_text16be() routines, and for sqlite3_result_text64()
+** when the encoding is not UTF8, if the input UTF16 begins with a
+** byte-order mark (BOM, U+FEFF) then the BOM is removed from the
+** string and the rest of the string is interpreted according to the
+** byte-order specified by the BOM.  ^The byte-order specified by
+** the BOM at the beginning of the text overrides the byte-order
+** specified by the interface procedure.  ^So, for example, if
+** sqlite3_result_text16le() is invoked with text that begins
+** with bytes 0xfe, 0xff (a big-endian byte-order mark) then the
+** first two bytes of input are skipped and the remaining input
+** is interpreted as UTF16BE text.
+**
+** ^For UTF16 input text to the sqlite3_result_text16(),
+** sqlite3_result_text16be(), sqlite3_result_text16le(), and
+** sqlite3_result_text64() routines, if the text contains invalid
+** UTF16 characters, the invalid characters might be converted
+** into the unicode replacement character, U+FFFD.
+**
+** ^The sqlite3_result_value() interface sets the result of
+** the application-defined function to be a copy of the
+** [unprotected sqlite3_value] object specified by the 2nd parameter.  ^The
+** sqlite3_result_value() interface makes a copy of the [sqlite3_value]
+** so that the [sqlite3_value] specified in the parameter may change or
+** be deallocated after sqlite3_result_value() returns without harm.
+** ^A [protected sqlite3_value] object may always be used where an
+** [unprotected sqlite3_value] object is required, so either
+** kind of [sqlite3_value] object can be used with this interface.
+**
+** ^The sqlite3_result_pointer(C,P,T,D) interface sets the result to an
+** SQL NULL value, just like [sqlite3_result_null(C)], except that it
+** also associates the host-language pointer P or type T with that 
+** NULL value such that the pointer can be retrieved within an
+** [application-defined SQL function] using [sqlite3_value_pointer()].
+** ^If the D parameter is not NULL, then it is a pointer to a destructor
+** for the P parameter.  ^SQLite invokes D with P as its only argument
+** when SQLite is finished with P.  The T parameter should be a static
+** string and preferably a string literal. The sqlite3_result_pointer()
+** routine is part of the [pointer passing interface] added for SQLite 3.20.0.

+** ^The [SQLITE_UTF16_ALIGNED] value for eTextRep forces strings to begin

+**
+** ^The fourth argument, pArg, is an application data pointer that is passed

+** CAPI3REF: Virtual Table Indexing Information
+** KEYWORDS: sqlite3_index_info
+**
+** The sqlite3_index_info structure and its substructures is used as part
+** of the [virtual table] interface to
+** pass information into and receive the reply from the [xBestIndex]
+** method of a [virtual table module].  The fields under **Inputs** are the
+** inputs to xBestIndex and are read-only.  xBestIndex inserts its
+** results into the **Outputs** fields.
+**
+** ^(The aConstraint[] array records WHERE clause constraints of the form:
+**
+** <blockquote>column OP expr</blockquote>
+**
+** where OP is =, &lt;, &lt;=, &gt;, or &gt;=.)^  ^(The particular operator is
+** stored in aConstraint[].op using one of the
+** [SQLITE_INDEX_CONSTRAINT_EQ | SQLITE_INDEX_CONSTRAINT_ values].)^
+** ^(The index of the column is stored in
+** aConstraint[].iColumn.)^  ^(aConstraint[].usable is TRUE if the
+** expr on the right-hand side can be evaluated (and thus the constraint
+** is usable) and false if it cannot.)^
+**
+** ^The optimizer automatically inverts terms of the form "expr OP column"
+** and makes other simplifications to the WHERE clause in an attempt to
+** get as many WHERE clause terms into the form shown above as possible.
+** ^The aConstraint[] array only reports WHERE clause terms that are
+** relevant to the particular virtual table being queried.
+**
+** ^Information about the ORDER BY clause is stored in aOrderBy[].
+** ^Each term of aOrderBy records a column of the ORDER BY clause.
+**
+** The colUsed field indicates which columns of the virtual table may be
+** required by the current scan. Virtual table columns are numbered from
+** zero in the order in which they appear within the CREATE TABLE statement
+** passed to sqlite3_declare_vtab(). For the first 63 columns (columns 0-62),
+** the corresponding bit is set within the colUsed mask if the column may be
+** required by SQLite. If the table has at least 64 columns and any column
+** to the right of the first 63 is required, then bit 63 of colUsed is also
+** set. In other words, column iCol may be required if the expression
+** (colUsed & ((sqlite3_uint64)1 << (iCol>=63 ? 63 : iCol))) evaluates to 
+** non-zero.
+**
+** The [xBestIndex] method must fill aConstraintUsage[] with information
+** about what parameters to pass to xFilter.  ^If argvIndex>0 then
+** the right-hand side of the corresponding aConstraint[] is evaluated
+** and becomes the argvIndex-th entry in argv.  ^(If aConstraintUsage[].omit
+** is true, then the constraint is assumed to be fully handled by the
+** virtual table and might not be checked again by the byte code.)^ ^(The
+** aConstraintUsage[].omit flag is an optimization hint. When the omit flag
+** is left in its default setting of false, the constraint will always be
+** checked separately in byte code.  If the omit flag is change to true, then
+** the constraint may or may not be checked in byte code.  In other words,
+** when the omit flag is true there is no guarantee that the constraint will
+** not be checked again using byte code.)^
+**
+** ^The idxNum and idxPtr values are recorded and passed into the
+** [xFilter] method.
+** ^[sqlite3_free()] is used to free idxPtr if and only if
+** needToFreeIdxPtr is true.
+**
+** ^The orderByConsumed means that output from [xFilter]/[xNext] will occur in
+** the correct order to satisfy the ORDER BY clause so that no separate
+** sorting step is required.
+**
+** ^The estimatedCost value is an estimate of the cost of a particular
+** strategy. A cost of N indicates that the cost of the strategy is similar
+** to a linear scan of an SQLite table with N rows. A cost of log(N) 
+** indicates that the expense of the operation is similar to that of a
+** binary search on a unique indexed field of an SQLite table with N rows.
+**
+** ^The estimatedRows value is an estimate of the number of rows that
+** will be returned by the strategy.
+**
+** The xBestIndex method may optionally populate the idxFlags field with a 
+** mask of SQLITE_INDEX_SCAN_* flags. Currently there is only one such flag -
+** SQLITE_INDEX_SCAN_UNIQUE. If the xBestIndex method sets this flag, SQLite
+** assumes that the strategy may visit at most one row. 
+**
+** Additionally, if xBestIndex sets the SQLITE_INDEX_SCAN_UNIQUE flag, then
+** SQLite also assumes that if a call to the xUpdate() method is made as
+** part of the same statement to delete or update a virtual table row and the
+** implementation returns SQLITE_CONSTRAINT, then there is no need to rollback
+** any database changes. In other words, if the xUpdate() returns
+** SQLITE_CONSTRAINT, the database contents must be exactly as they were
+** before xUpdate was called. By contrast, if SQLITE_INDEX_SCAN_UNIQUE is not
+** set and xUpdate returns SQLITE_CONSTRAINT, any database changes made by
+** the xUpdate method are automatically rolled back by SQLite.
+**
+** IMPORTANT: The estimatedRows field was added to the sqlite3_index_info
+** structure for SQLite [version 3.8.2] ([dateof:3.8.2]). 
+** If a virtual table extension is
+** used with an SQLite version earlier than 3.8.2, the results of attempting 
+** to read or write the estimatedRows field are undefined (but are likely 
+** to include crashing the application). The estimatedRows field should
+** therefore only be used if [sqlite3_libversion_number()] returns a
+** value greater than or equal to 3008002. Similarly, the idxFlags field
+** was added for [version 3.9.0] ([dateof:3.9.0]). 
+** It may therefore only be used if
+** sqlite3_libversion_number() returns a value greater than or equal to

+**
+** The SQLite source code contains multiple implementations

+** implementations are available in the SQLite core:
+**
+** <ul>
+** <li>   SQLITE_MUTEX_PTHREADS
+** <li>   SQLITE_MUTEX_W32
+** <li>   SQLITE_MUTEX_NOOP

+** that does no real locking and is appropriate for use in
+** a single-threaded application.  The SQLITE_MUTEX_PTHREADS and
+** SQLITE_MUTEX_W32 implementations are appropriate for use on Unix
+** and Windows.
+**
+** If SQLite is compiled with the SQLITE_MUTEX_APPDEF preprocessor
+** macro defined (with "-DSQLITE_MUTEX_APPDEF=1"), then no mutex
+** implementation is included with the library. In this case the
+** application must supply a custom mutex implementation using the
+** [SQLITE_CONFIG_MUTEX] option of the sqlite3_config() function
+** before calling sqlite3_initialize() or any other public sqlite3_
+** function that calls sqlite3_initialize().
+**
+** ^The sqlite3_mutex_alloc() routine allocates a new
+** mutex and returns a pointer to it. ^The sqlite3_mutex_alloc()
+** routine returns NULL if it is unable to allocate the requested
+** mutex.  The argument to sqlite3_mutex_alloc() must one of these
+** integer constants:
+**
+** <ul>
+** <li>  SQLITE_MUTEX_FAST
+** <li>  SQLITE_MUTEX_RECURSIVE
+** <li>  SQLITE_MUTEX_STATIC_MASTER
+** <li>  SQLITE_MUTEX_STATIC_MEM

+** <li>  SQLITE_MUTEX_STATIC_VFS3
+** </ul>
+**
+** ^The first two constants (SQLITE_MUTEX_FAST and SQLITE_MUTEX_RECURSIVE)
+** cause sqlite3_mutex_alloc() to create
+** a new mutex.  ^The new mutex is recursive when SQLITE_MUTEX_RECURSIVE
+** is used but not necessarily so when SQLITE_MUTEX_FAST is used.
+** The mutex implementation does not need to make a distinction
+** between SQLITE_MUTEX_RECURSIVE and SQLITE_MUTEX_FAST if it does
+** not want to.  SQLite will only request a recursive mutex in
+** cases where it really needs one.  If a faster non-recursive mutex
+** implementation is available on the host platform, the mutex subsystem
+** might return such a mutex in response to SQLITE_MUTEX_FAST.
+**
+** ^The other allowed parameters to sqlite3_mutex_alloc() (anything other
+** than SQLITE_MUTEX_FAST and SQLITE_MUTEX_RECURSIVE) each return
+** a pointer to a static preexisting mutex.  ^Nine static mutexes are
+** used by the current version of SQLite.  Future versions of SQLite
+** may add additional static mutexes.  Static mutexes are for internal
+** use by SQLite only.  Applications that use SQLite mutexes should
+** use only the dynamic mutexes returned by SQLITE_MUTEX_FAST or
+** SQLITE_MUTEX_RECURSIVE.
+**
+** ^Note that if one of the dynamic mutex parameters (SQLITE_MUTEX_FAST
+** or SQLITE_MUTEX_RECURSIVE) is used then sqlite3_mutex_alloc()
+** returns a different mutex on every call.  ^For the static
+** mutex types, the same mutex is returned on every call that has
+** the same type number.
+**
+** ^The sqlite3_mutex_free() routine deallocates a previously
+** allocated dynamic mutex.  Attempting to deallocate a static
+** mutex results in undefined behavior.
+**
+** ^The sqlite3_mutex_enter() and sqlite3_mutex_try() routines attempt
+** to enter a mutex.  ^If another thread is already within the mutex,
+** sqlite3_mutex_enter() will block and sqlite3_mutex_try() will return

+** implementation for specialized deployments or systems for which SQLite
+** does not provide a suitable implementation. In this case, the application
+** creates and populates an instance of this structure to pass

+** Additionally, an instance of this structure can be used as an
+** output variable when querying the system for the current mutex
+** implementation, using the [SQLITE_CONFIG_GETMUTEX] option.
+**
+** ^The xMutexInit method defined by this structure is invoked as
+** part of system initialization by the sqlite3_initialize() function.
+** ^The xMutexInit routine is called by SQLite exactly once for each
+** effective call to [sqlite3_initialize()].
+**
+** ^The xMutexEnd method defined by this structure is invoked as
+** part of system shutdown by the sqlite3_shutdown() function. The
+** implementation of this method is expected to release all outstanding
+** resources obtained by the mutex methods implementation, especially
+** those obtained by the xMutexInit method.  ^The xMutexEnd()
+** interface is invoked exactly once for each call to [sqlite3_shutdown()].
+**
+** ^(The remaining seven methods defined by this structure (xMutexAlloc,
+** xMutexFree, xMutexEnter, xMutexTry, xMutexLeave, xMutexHeld and
+** xMutexNotheld) implement the following interfaces (respectively):
+**
+** <ul>

+**   <li>  [sqlite3_mutex_notheld()] </li>

+** The only difference is that the public sqlite3_XXX functions enumerated

+** by this structure are not required to handle this case. The results
+** of passing a NULL pointer instead of a valid mutex handle are undefined
+** (i.e. it is acceptable to provide an implementation that segfaults if
+** it is passed a NULL pointer).

+** and its associates).  Similarly, xMutexAlloc() must not use SQLite memory
+** allocation for a static mutex.  ^However xMutexAlloc() may use SQLite

+**
+** ^SQLite will invoke the xMutexEnd() method when [sqlite3_shutdown()] is

+** CAPI3REF: SQL Keyword Checking
+**
+** These routines provide access to the set of SQL language keywords 
+** recognized by SQLite.  Applications can uses these routines to determine
+** whether or not a specific identifier needs to be escaped (for example,
+** by enclosing in double-quotes) so as not to confuse the parser.
+**
+** The sqlite3_keyword_count() interface returns the number of distinct
+** keywords understood by SQLite.
+**
+** The sqlite3_keyword_name(N,Z,L) interface finds the N-th keyword and
+** makes *Z point to that keyword expressed as UTF8 and writes the number
+** of bytes in the keyword into *L.  The string that *Z points to is not
+** zero-terminated.  The sqlite3_keyword_name(N,Z,L) routine returns
+** SQLITE_OK if N is within bounds and SQLITE_ERROR if not. If either Z
+** or L are NULL or invalid pointers then calls to
+** sqlite3_keyword_name(N,Z,L) result in undefined behavior.
+**
+** The sqlite3_keyword_check(Z,L) interface checks to see whether or not
+** the L-byte UTF8 identifier that Z points to is a keyword, returning non-zero
+** if it is and zero if not.
+**
+** The parser used by SQLite is forgiving.  It is often possible to use
+** a keyword as an identifier as long as such use does not result in a
+** parsing ambiguity.  For example, the statement
+** "CREATE TABLE BEGIN(REPLACE,PRAGMA,END);" is accepted by SQLite, and
+** creates a new table named "BEGIN" with three columns named
+** "REPLACE", "PRAGMA", and "END".  Nevertheless, best practice is to avoid
+** using keywords as identifiers.  Common techniques used to avoid keyword
+** name collisions include:
+** <ul>
+** <li> Put all identifier names inside double-quotes.  This is the official
+**      SQL way to escape identifier names.
+** <li> Put identifier names inside &#91;...&#93;.  This is not standard SQL,
+**      but it is what SQL Server does and so lots of programmers use this
+**      technique.
+** <li> Begin every identifier with the letter "Z" as no SQL keywords start
+**      with "Z".
+** <li> Include a digit somewhere in every identifier name.
+** </ul>
+**
+** Note that the number of keywords understood by SQLite can depend on
+** compile-time options.  For example, "VACUUM" is not a keyword if
+** SQLite is compiled with the [-DSQLITE_OMIT_VACUUM] option.  Also,
+** new keywords may be added to future releases of SQLite.

+**
+** ^(The [sqlite3_config]([SQLITE_CONFIG_PCACHE2], ...) interface can
+** register an alternative page cache implementation by passing in an 
+** instance of the sqlite3_pcache_methods2 structure.)^
+** In many applications, most of the heap memory allocated by 
+** SQLite is used for the page cache.
+** By implementing a 
+** custom page cache using this API, an application can better control
+** the amount of memory consumed by SQLite, the way in which 
+** that memory is allocated and released, and the policies used to 
+** determine exactly which parts of a database file are cached and for 
+** how long.
+**
+** The alternative page cache mechanism is an
+** extreme measure that is only needed by the most demanding applications.
+** The built-in page cache is recommended for most uses.
+**
+** ^(The contents of the sqlite3_pcache_methods2 structure are copied to an
+** internal buffer by SQLite within the call to [sqlite3_config].  Hence
+** the application may discard the parameter after the call to
+** [sqlite3_config()] returns.)^
+**
+** [[the xInit() page cache method]]
+** ^(The xInit() method is called once for each effective 
+** call to [sqlite3_initialize()])^
+** (usually only once during the lifetime of the process). ^(The xInit()
+** method is passed a copy of the sqlite3_pcache_methods2.pArg value.)^
+** The intent of the xInit() method is to set up global data structures 
+** required by the custom page cache implementation. 
+** ^(If the xInit() method is NULL, then the 
+** built-in default page cache is used instead of the application defined
+** page cache.)^
+**
+** [[the xShutdown() page cache method]]
+** ^The xShutdown() method is called by [sqlite3_shutdown()].
+** It can be used to clean up 
+** any outstanding resources before process shutdown, if required.
+** ^The xShutdown() method may be NULL.
+**
+** ^SQLite automatically serializes calls to the xInit method,
+** so the xInit method need not be threadsafe.  ^The
+** xShutdown method is only called from [sqlite3_shutdown()] so it does
+** not need to be threadsafe either.  All other methods must be threadsafe
+** in multithreaded applications.
+**
+** ^SQLite will never invoke xInit() more than once without an intervening
+** call to xShutdown().
+**
+** [[the xCreate() page cache methods]]
+** ^SQLite invokes the xCreate() method to construct a new cache instance.
+** SQLite will typically create one cache instance for each open database file,
+** though this is not guaranteed. ^The
+** first parameter, szPage, is the size in bytes of the pages that must
+** be allocated by the cache.  ^szPage will always a power of two.  ^The
+** second parameter szExtra is a number of bytes of extra storage 
+** associated with each page cache entry.  ^The szExtra parameter will
+** a number less than 250.  SQLite will use the
+** extra szExtra bytes on each page to store metadata about the underlying
+** database page on disk.  The value passed into szExtra depends
+** on the SQLite version, the target platform, and how SQLite was compiled.
+** ^The third argument to xCreate(), bPurgeable, is true if the cache being
+** created will be used to cache database pages of a file stored on disk, or
+** false if it is used for an in-memory database. The cache implementation
+** does not have to do anything special based with the value of bPurgeable;
+** it is purely advisory.  ^On a cache where bPurgeable is false, SQLite will
+** never invoke xUnpin() except to deliberately delete a page.
+** ^In other words, calls to xUnpin() on a cache with bPurgeable set to
+** false will always have the "discard" flag set to true.  
+** ^Hence, a cache created with bPurgeable false will
+** never contain any unpinned pages.
+**
+** [[the xCachesize() page cache method]]
+** ^(The xCachesize() method may be called at any time by SQLite to set the
+** suggested maximum cache-size (number of pages stored by) the cache
+** instance passed as the first argument. This is the value configured using
+** the SQLite "[PRAGMA cache_size]" command.)^  As with the bPurgeable
+** parameter, the implementation is not required to do anything with this
+** value; it is advisory only.
+**
+** [[the xPagecount() page cache methods]]
+** The xPagecount() method must return the number of pages currently
+** stored in the cache, both pinned and unpinned.
+** 
+** [[the xFetch() page cache methods]]
+** The xFetch() method locates a page in the cache and returns a pointer to 
+** an sqlite3_pcache_page object associated with that page, or a NULL pointer.
+** The pBuf element of the returned sqlite3_pcache_page object will be a
+** pointer to a buffer of szPage bytes used to store the content of a 
+** single database page.  The pExtra element of sqlite3_pcache_page will be
+** a pointer to the szExtra bytes of extra storage that SQLite has requested
+** for each entry in the page cache.
+**
+** The page to be fetched is determined by the key. ^The minimum key value
+** is 1.  After it has been retrieved using xFetch, the page is considered
+** to be "pinned".
+**
+** If the requested page is already in the page cache, then the page cache
+** implementation must return a pointer to the page buffer with its content
+** intact.  If the requested page is not already in the cache, then the
+** cache implementation should use the value of the createFlag
+** parameter to help it determined what action to take:
+**
+** <table border=1 width=85% align=center>
+** <tr><th> createFlag <th> Behavior when page is not already in cache
+** <tr><td> 0 <td> Do not allocate a new page.  Return NULL.
+** <tr><td> 1 <td> Allocate a new page if it easy and convenient to do so.
+**                 Otherwise return NULL.
+** <tr><td> 2 <td> Make every effort to allocate a new page.  Only return
+**                 NULL if allocating a new page is effectively impossible.
+** </table>
+**
+** ^(SQLite will normally invoke xFetch() with a createFlag of 0 or 1.  SQLite
+** will only use a createFlag of 2 after a prior call with a createFlag of 1
+** failed.)^  In between the xFetch() calls, SQLite may
+** attempt to unpin one or more cache pages by spilling the content of
+** pinned pages to disk and synching the operating system disk cache.
+**
+** [[the xUnpin() page cache method]]
+** ^xUnpin() is called by SQLite with a pointer to a currently pinned page
+** as its second argument.  If the third parameter, discard, is non-zero,
+** then the page must be evicted from the cache.
+** ^If the discard parameter is
+** zero, then the page may be discarded or retained at the discretion of
+** page cache implementation. ^The page cache implementation
+** may choose to evict unpinned pages at any time.
+**
+** The cache must not perform any reference counting. A single 
+** call to xUnpin() unpins the page regardless of the number of prior calls 
+** to xFetch().
+**
+** [[the xRekey() page cache methods]]
+** The xRekey() method is used to change the key value associated with the
+** page passed as the second argument. If the cache
+** previously contains an entry associated with newKey, it must be
+** discarded. ^Any prior cache entry associated with newKey is guaranteed not
+** to be pinned.
+**
+** When SQLite calls the xTruncate() method, the cache must discard all
+** existing cache entries with page numbers (keys) greater than or equal
+** to the value of the iLimit parameter passed to xTruncate(). If any
+** of these pages are pinned, they are implicitly unpinned, meaning that
+** they can be safely discarded.
+**
+** [[the xDestroy() page cache method]]
+** ^The xDestroy() method is used to delete a cache allocated by xCreate().
+** All resources associated with the specified cache should be freed. ^After
+** calling the xDestroy() method, SQLite considers the [sqlite3_pcache*]
+** handle invalid, and will not use it with any other sqlite3_pcache_methods2
+** functions.
+**
+** [[the xShrink() page cache method]]
+** ^SQLite invokes the xShrink() method when it wants the page cache to
+** free up as much of heap memory as possible.  The page cache implementation
+** is not obligated to free any memory, but well-behaved implementations should
+** do their best.

+** If this happens, then the specified callback is invoked immediately,
+** from within the call to sqlite3_unlock_notify().)^
+**
+** ^If the blocked connection is attempting to obtain a write-lock on a

+** the other connections to use as the blocking connection.
+**
+** ^(There may be at most one unlock-notify callback registered by a

+**
+** ^Unless deadlock is detected (see below), sqlite3_unlock_notify() always

+**
+** <b>Callback Invocation Details</b>
+**
+** When an unlock-notify callback is registered, the application provides a 
+** single void* pointer that is passed to the callback when it is invoked.
+** However, the signature of the callback function allows SQLite to pass
+** it an array of void* context pointers. The first argument passed to
+** an unlock-notify callback is a pointer to an array of void* pointers,
+** and the second is the number of entries in the array.
+**
+** When a blocking connection's transaction is concluded, there may be
+** more than one blocked connection that has registered for an unlock-notify
+** callback. ^If two or more such blocked connections have specified the
+** same callback function, then instead of invoking the callback function
+** multiple times, it is invoked once with the set of void* context pointers
+** specified by the blocked connections bundled together into an array.
+** This gives the application an opportunity to prioritize any actions 
+** related to the set of unblocked database connections.
+**
+** <b>Deadlock Detection</b>
+**
+** Assuming that after registering for an unlock-notify callback a 
+** database waits for the callback to be issued before taking any further
+** action (a reasonable assumption), then using this API may cause the
+** application to deadlock. For example, if connection X is waiting for
+** connection Y's transaction to be concluded, and similarly connection
+** Y is waiting on connection X's transaction, then neither connection
+** will proceed and the system may remain deadlocked indefinitely.
+**
+** To avoid this scenario, the sqlite3_unlock_notify() performs deadlock
+** detection. ^If a given call to sqlite3_unlock_notify() would put the
+** system in a deadlocked state, then SQLITE_LOCKED is returned and no
+** unlock-notify callback is registered. The system is said to be in
+** a deadlocked state if connection A has registered for an unlock-notify
+** callback on the conclusion of connection B's transaction, and connection
+** B has itself registered for an unlock-notify callback when connection
+** A's transaction is concluded. ^Indirect deadlock is also detected, so
+** the system is also considered to be deadlocked if connection B has
+** registered for an unlock-notify callback on the conclusion of connection
+** C's transaction, where connection C is waiting on connection A. ^Any
+** number of levels of indirection are allowed.
+**
+** <b>The "DROP TABLE" Exception</b>
+**
+** When a call to [sqlite3_step()] returns SQLITE_LOCKED, it is almost 
+** always appropriate to call sqlite3_unlock_notify(). There is however,
+** one exception. When executing a "DROP TABLE" or "DROP INDEX" statement,
+** SQLite checks if there are any currently executing SELECT statements
+** that belong to the same connection. If there are, SQLITE_LOCKED is
+** returned. In this case there is no "blocking connection", so invoking
+** sqlite3_unlock_notify() results in the unlock-notify callback being
+** invoked immediately. If the application then re-attempts the "DROP TABLE"
+** or "DROP INDEX" query, an infinite loop might be the result.
+**
+** One way around this problem is to check the extended error code returned
+** by an sqlite3_step() call. ^(If there is a blocking connection, then the
+** extended error code is set to SQLITE_LOCKED_SHAREDCACHE. Otherwise, in
+** the special "DROP TABLE/INDEX" case, the extended error code is just 
+** SQLITE_LOCKED.)^

+**  <pre>
+**  &nbsp;     CREATE TABLE sqlite_stat1(tbl,idx,stat)  
+**  </pre>
+**
+** Even though sqlite_stat1 does not have a PRIMARY KEY, changes are 
+** recorded for it as if the PRIMARY KEY is (tbl,idx). Additionally, changes 
+** are recorded for rows for which (idx IS NULL) is true. However, for such
+** rows a zero-length blob (SQL value X'') is stored in the changeset or
+** patchset instead of a NULL value. This allows such changesets to be
+** manipulated by legacy implementations of sqlite3changeset_invert(),
+** concat() and similar.
+**
+** The sqlite3changeset_apply() function automatically converts the 
+** zero-length blob back to a NULL value when updating the sqlite_stat1
+** table. However, if the application calls sqlite3changeset_new(),
+** sqlite3changeset_old() or sqlite3changeset_conflict on a changeset 
+** iterator directly (including on a changeset iterator passed to a
+** conflict-handler callback) then the X'' value is returned. The application
+** must translate X'' to NULL itself if required.
+**
+** Legacy (older than 3.22.0) versions of the sessions module cannot capture
+** changes made to the sqlite_stat1 table. Legacy versions of the
+** sqlite3changeset_apply() function silently ignore any modifications to the
+** sqlite_stat1 table that are part of a changeset or patchset.

+** SQLITE_OK. If an error occurs, set both *ppChangeset and *pnChangeset to
+** zero and return an SQLite error code.
+**
+** A changeset consists of zero or more INSERT, UPDATE and/or DELETE changes,
+** each representing a change to a single row of an attached table. An INSERT
+** change contains the values of each field of a new database row. A DELETE
+** contains the original values of each field of a deleted database row. An
+** UPDATE change contains the original values of each field of an updated
+** database row along with the updated values for each updated non-primary-key
+** column. It is not possible for an UPDATE change to represent a change that
+** modifies the values of primary key columns. If such a change is made, it
+** is represented in a changeset as a DELETE followed by an INSERT.
+**
+** Changes are not recorded for rows that have NULL values stored in one or 
+** more of their PRIMARY KEY columns. If such a row is inserted or deleted,
+** no corresponding change is present in the changesets returned by this
+** function. If an existing row with one or more NULL values stored in
+** PRIMARY KEY columns is updated so that all PRIMARY KEY columns are non-NULL,
+** only an INSERT is appears in the changeset. Similarly, if an existing row
+** with non-NULL PRIMARY KEY values is updated so that one or more of its
+** PRIMARY KEY columns are set to NULL, the resulting changeset contains a
+** DELETE change only.
+**
+** The contents of a changeset may be traversed using an iterator created
+** using the [sqlite3changeset_start()] API. A changeset may be applied to
+** a database with a compatible schema using the [sqlite3changeset_apply()]
+** API.
+**
+** Within a changeset generated by this function, all changes related to a
+** single table are grouped together. In other words, when iterating through
+** a changeset or when applying a changeset to a database, all changes related
+** to a single table are processed before moving on to the next table. Tables
+** are sorted in the same order in which they were attached (or auto-attached)
+** to the sqlite3_session object. The order in which the changes related to
+** a single table are stored is undefined.
+**
+** Following a successful call to this function, it is the responsibility of
+** the caller to eventually free the buffer that *ppChangeset points to using
+** [sqlite3_free()].
+**
+** <h3>Changeset Generation</h3>
+**
+** Once a table has been attached to a session object, the session object
+** records the primary key values of all new rows inserted into the table.
+** It also records the original primary key and other column values of any
+** deleted or updated rows. For each unique primary key value, data is only
+** recorded once - the first time a row with said primary key is inserted,
+** updated or deleted in the lifetime of the session.
+**
+** There is one exception to the previous paragraph: when a row is inserted,
+** updated or deleted, if one or more of its primary key columns contain a
+** NULL value, no record of the change is made.
+**
+** The session object therefore accumulates two types of records - those
+** that consist of primary key values only (created when the user inserts
+** a new record) and those that consist of the primary key values and the
+** original values of other table columns (created when the users deletes
+** or updates a record).
+**
+** When this function is called, the requested changeset is created using
+** both the accumulated records and the current contents of the database
+** file. Specifically:
+**
+** <ul>
+**   <li> For each record generated by an insert, the database is queried
+**        for a row with a matching primary key. If one is found, an INSERT
+**        change is added to the changeset. If no such row is found, no change 
+**        is added to the changeset.
+**
+**   <li> For each record generated by an update or delete, the database is 
+**        queried for a row with a matching primary key. If such a row is
+**        found and one or more of the non-primary key fields have been
+**        modified from their original values, an UPDATE change is added to 
+**        the changeset. Or, if no such row is found in the table, a DELETE 
+**        change is added to the changeset. If there is a row with a matching
+**        primary key in the database, but all fields contain their original
+**        values, no change is added to the changeset.
+** </ul>
+**
+** This means, amongst other things, that if a row is inserted and then later
+** deleted while a session object is active, neither the insert nor the delete
+** will be present in the changeset. Or if a row is deleted and then later a 
+** row with the same primary key values inserted while a session object is
+** active, the resulting changeset will contain an UPDATE change instead of
+** a DELETE and an INSERT.
+**
+** When a session object is disabled (see the [sqlite3session_enable()] API),
+** it does not accumulate records when rows are inserted, updated or deleted.
+** This may appear to have some counter-intuitive effects if a single row
+** is written to more than once during a session. For example, if a row
+** is inserted while a session object is enabled, then later deleted while 
+** the same session object is disabled, no INSERT record will appear in the
+** changeset, even though the delete took place while the session was disabled.
+** Or, if one field of a row is updated while a session is disabled, and 
+** another field of the same row is updated while the session is enabled, the
+** resulting changeset will contain an UPDATE change that updates both fields.

+** used to update the table in database zFrom (call this the "from-table") 
+** so that its content is the same as the table attached to the session

+**
+** <dl>
+** <dt>DELETE Changes<dd>
+**   For each DELETE change, the function checks if the target database 
+**   contains a row with the same primary key value (or values) as the 
+**   original row values stored in the changeset. If it does, and the values 
+**   stored in all non-primary key columns also match the values stored in 
+**   the changeset the row is deleted from the target database.
+**
+**   If a row with matching primary key values is found, but one or more of
+**   the non-primary key fields contains a value different from the original
+**   row value stored in the changeset, the conflict-handler function is
+**   invoked with [SQLITE_CHANGESET_DATA] as the second argument. If the
+**   database table has more columns than are recorded in the changeset,
+**   only the values of those non-primary key fields are compared against
+**   the current database contents - any trailing database table columns
+**   are ignored.
+**
+**   If no row with matching primary key values is found in the database,
+**   the conflict-handler function is invoked with [SQLITE_CHANGESET_NOTFOUND]
+**   passed as the second argument.
+**
+**   If the DELETE operation is attempted, but SQLite returns SQLITE_CONSTRAINT
+**   (which can only happen if a foreign key constraint is violated), the
+**   conflict-handler function is invoked with [SQLITE_CHANGESET_CONSTRAINT]
+**   passed as the second argument. This includes the case where the DELETE
+**   operation is attempted because an earlier call to the conflict handler
+**   function returned [SQLITE_CHANGESET_REPLACE].
+**
+** <dt>INSERT Changes<dd>
+**   For each INSERT change, an attempt is made to insert the new row into
+**   the database. If the changeset row contains fewer fields than the
+**   database table, the trailing fields are populated with their default
+**   values.
+**
+**   If the attempt to insert the row fails because the database already 
+**   contains a row with the same primary key values, the conflict handler
+**   function is invoked with the second argument set to 
+**   [SQLITE_CHANGESET_CONFLICT].
+**
+**   If the attempt to insert the row fails because of some other constraint
+**   violation (e.g. NOT NULL or UNIQUE), the conflict handler function is 
+**   invoked with the second argument set to [SQLITE_CHANGESET_CONSTRAINT].
+**   This includes the case where the INSERT operation is re-attempted because 
+**   an earlier call to the conflict handler function returned 
+**   [SQLITE_CHANGESET_REPLACE].
+**
+** <dt>UPDATE Changes<dd>
+**   For each UPDATE change, the function checks if the target database 
+**   contains a row with the same primary key value (or values) as the 
+**   original row values stored in the changeset. If it does, and the values 
+**   stored in all modified non-primary key columns also match the values
+**   stored in the changeset the row is updated within the target database.
+**
+**   If a row with matching primary key values is found, but one or more of
+**   the modified non-primary key fields contains a value different from an
+**   original row value stored in the changeset, the conflict-handler function
+**   is invoked with [SQLITE_CHANGESET_DATA] as the second argument. Since
+**   UPDATE changes only contain values for non-primary key fields that are
+**   to be modified, only those fields need to match the original values to
+**   avoid the SQLITE_CHANGESET_DATA conflict-handler callback.
+**
+**   If no row with matching primary key values is found in the database,
+**   the conflict-handler function is invoked with [SQLITE_CHANGESET_NOTFOUND]
+**   passed as the second argument.
+**
+**   If the UPDATE operation is attempted, but SQLite returns 
+**   SQLITE_CONSTRAINT, the conflict-handler function is invoked with 
+**   [SQLITE_CHANGESET_CONSTRAINT] passed as the second argument.
+**   This includes the case where the UPDATE operation is attempted after 
+**   an earlier call to the conflict handler function returned
+**   [SQLITE_CHANGESET_REPLACE].

+**
+** It is safe to execute SQL statements, including those that write to the
+** table that the callback related to, from within the xConflict callback.
+** This can be used to further customize the application's conflict
+** resolution strategy.
+**
+** All changes made by these functions are enclosed in a savepoint transaction.
+** If any other error (aside from a constraint failure when attempting to
+** write to the target database) occurs, then the savepoint transaction is
+** rolled back, restoring the target database to its original state, and an 
+** SQLite error code returned.
+**
+** If the output parameters (ppRebase) and (pnRebase) are non-NULL and
+** the input is a changeset (not a patchset), then sqlite3changeset_apply_v2()
+** may set (*ppRebase) to point to a "rebase" that may be used with the

+** CAPI3REF: Rebasing changesets
+** EXPERIMENTAL
+**
+** Suppose there is a site hosting a database in state S0. And that
+** modifications are made that move that database to state S1 and a
+** changeset recorded (the "local" changeset). Then, a changeset based
+** on S0 is received from another site (the "remote" changeset) and 
+** applied to the database. The database is then in state 
+** (S1+"remote"), where the exact state depends on any conflict
+** resolution decisions (OMIT or REPLACE) made while applying "remote".
+** Rebasing a changeset is to update it to take those conflict 
+** resolution decisions into account, so that the same conflicts
+** do not have to be resolved elsewhere in the network. 
+**
+** For example, if both the local and remote changesets contain an
+** INSERT of the same key on "CREATE TABLE t1(a PRIMARY KEY, b)":
+**
+**   local:  INSERT INTO t1 VALUES(1, 'v1');
+**   remote: INSERT INTO t1 VALUES(1, 'v2');
+**
+** and the conflict resolution is REPLACE, then the INSERT change is
+** removed from the local changeset (it was overridden). Or, if the
+** conflict resolution was "OMIT", then the local changeset is modified
+** to instead contain:
+**
+**           UPDATE t1 SET b = 'v2' WHERE a=1;
+**
+** Changes within the local changeset are rebased as follows:
+**
+** <dl>
+** <dt>Local INSERT<dd>
+**   This may only conflict with a remote INSERT. If the conflict 
+**   resolution was OMIT, then add an UPDATE change to the rebased
+**   changeset. Or, if the conflict resolution was REPLACE, add
+**   nothing to the rebased changeset.
+**
+** <dt>Local DELETE<dd>
+**   This may conflict with a remote UPDATE or DELETE. In both cases the
+**   only possible resolution is OMIT. If the remote operation was a
+**   DELETE, then add no change to the rebased changeset. If the remote
+**   operation was an UPDATE, then the old.* fields of change are updated
+**   to reflect the new.* values in the UPDATE.
+**
+** <dt>Local UPDATE<dd>
+**   This may conflict with a remote UPDATE or DELETE. If it conflicts
+**   with a DELETE, and the conflict resolution was OMIT, then the update
+**   is changed into an INSERT. Any undefined values in the new.* record
+**   from the update change are filled in using the old.* values from
+**   the conflicting DELETE. Or, if the conflict resolution was REPLACE,
+**   the UPDATE change is simply omitted from the rebased changeset.
+**
+**   If conflict is with a remote UPDATE and the resolution is OMIT, then
+**   the old.* values are rebased using the new.* values in the remote
+**   change. Or, if the resolution is REPLACE, then the change is copied
+**   into the rebased changeset with updates to columns also updated by
+**   the conflicting remote UPDATE removed. If this means no columns would 
+**   be updated, the change is omitted.
+** </dl>
+**
+** A local change may be rebased against multiple remote changes 
+** simultaneously. If a single key is modified by multiple remote 
+** changesets, they are combined as follows before the local changeset
+** is rebased:
+**
+** <ul>
+**    <li> If there has been one or more REPLACE resolutions on a
+**         key, it is rebased according to a REPLACE.
+**
+**    <li> If there have been no REPLACE resolutions on a key, then
+**         the local changeset is rebased according to the most recent
+**         of the OMIT resolutions.
+** </ul>
+**
+** Note that conflict resolutions from multiple remote changesets are 
+** combined on a per-field basis, not per-row. This means that in the 
+** case of multiple remote UPDATE operations, some fields of a single 
+** local change may be rebased for REPLACE while others are rebased for 
+** OMIT.
+**
+** In order to rebase a local changeset, the remote changeset must first
+** be applied to the local database using sqlite3changeset_apply_v2() and
+** the buffer of rebase information captured. Then:
+**
+** <ol>
+**   <li> An sqlite3_rebaser object is created by calling

+**   <li> The new object is configured with the rebase buffer obtained from
+**        sqlite3changeset_apply_v2() by calling sqlite3rebaser_configure().
+**        If the local changeset is to be rebased against multiple remote
+**        changesets, then sqlite3rebaser_configure() should be called
+**        multiple times, in the same order that the multiple
+**        sqlite3changeset_apply_v2() calls were made.

+** Non-streaming functions that accept changesets (or patchsets) as input
+** require that the entire changeset be stored in a single buffer in memory. 
+** Similarly, those that return a changeset or patchset do so by returning 
+** a pointer to a single large buffer allocated using sqlite3_malloc(). 
+** Normally this is convenient. However, if an application running in a 
+** low-memory environment is required to handle very large changesets, the
+** large contiguous memory allocations required can become onerous.
+**
+** In order to avoid this problem, instead of a single large buffer, input
+** is passed to a streaming API functions by way of a callback function that
+** the sessions module invokes to incrementally request input data as it is
+** required. In all cases, a pair of API function parameters such as
+**
+**  <pre>
+**  &nbsp;     int nChangeset,
+**  &nbsp;     void *pChangeset,
+**  </pre>
+**
+** Is replaced by:

+**  <pre>
+**  &nbsp;     int (*xInput)(void *pIn, void *pData, int *pnData),
+**  &nbsp;     void *pIn,
+**  </pre>
+**
+** Each time the xInput callback is invoked by the sessions module, the first
+** argument passed is a copy of the supplied pIn context pointer. The second 
+** argument, pData, points to a buffer (*pnData) bytes in size. Assuming no 
+** error occurs the xInput method should copy up to (*pnData) bytes of data 
+** into the buffer and set (*pnData) to the actual number of bytes copied 
+** before returning SQLITE_OK. If the input is completely exhausted, (*pnData) 
+** should be set to zero to indicate this. Or, if an error occurs, an SQLite 
+** error code should be returned. In all cases, if an xInput callback returns
+** an error, all processing is abandoned and the streaming API function
+** returns a copy of the error code to the caller.
+**
+** In the case of sqlite3changeset_start_strm(), the xInput callback may be
+** invoked by the sessions module at any point during the lifetime of the
+** iterator. If such an xInput callback returns an error, the iterator enters
+** an error state, whereby all subsequent calls to iterator functions 
+** immediately fail with the same error code as returned by xInput.
+**
+** Similarly, streaming API functions that return changesets (or patchsets)
+** return them in chunks by way of a callback function instead of via a
+** pointer to a single large buffer. In this case, a pair of parameters such
+** as:
+**
+**  <pre>
+**  &nbsp;     int *pnChangeset,
+**  &nbsp;     void **ppChangeset,
+**  </pre>

+**  <pre>
+**  &nbsp;     int (*xOutput)(void *pOut, const void *pData, int nData),
+**  &nbsp;     void *pOut
+**  </pre>
+**
+** The xOutput callback is invoked zero or more times to return data to
+** the application. The first parameter passed to each call is a copy of the
+** pOut pointer supplied by the application. The second parameter, pData,
+** points to a buffer nData bytes in size containing the chunk of output
+** data being returned. If the xOutput callback successfully processes the
+** supplied data, it should return SQLITE_OK to indicate success. Otherwise,
+** it should return some other SQLite error code. In this case processing
+** is immediately abandoned and the streaming API function returns a copy
+** of the xOutput error code to the application.
+**
+** The sessions module never invokes an xOutput callback with the third

+** EXTENSION API FUNCTIONS
+**
+** xUserData(pFts):
+**   Return a copy of the context pointer the extension function was 
+**   registered with.
+**
+** xColumnTotalSize(pFts, iCol, pnToken):
+**   If parameter iCol is less than zero, set output variable *pnToken
+**   to the total number of tokens in the FTS5 table. Or, if iCol is
+**   non-negative but less than the number of columns in the table, return
+**   the total number of tokens in column iCol, considering all rows in 
+**   the FTS5 table.
+**
+**   If parameter iCol is greater than or equal to the number of columns
+**   in the table, SQLITE_RANGE is returned. Or, if an error occurs (e.g.
+**   an OOM condition or IO error), an appropriate SQLite error code is 
+**   returned.
+**
+** xColumnCount(pFts):
+**   Return the number of columns in the table.
+**
+** xColumnSize(pFts, iCol, pnToken):
+**   If parameter iCol is less than zero, set output variable *pnToken
+**   to the total number of tokens in the current row. Or, if iCol is
+**   non-negative but less than the number of columns in the table, set
+**   *pnToken to the number of tokens in column iCol of the current row.
+**
+**   If parameter iCol is greater than or equal to the number of columns
+**   in the table, SQLITE_RANGE is returned. Or, if an error occurs (e.g.
+**   an OOM condition or IO error), an appropriate SQLite error code is 
+**   returned.
+**
+**   This function may be quite inefficient if used with an FTS5 table
+**   created with the "columnsize=0" option.
+**
+** xColumnText:
+**   This function attempts to retrieve the text of column iCol of the
+**   current document. If successful, (*pz) is set to point to a buffer
+**   containing the text in utf-8 encoding, (*pn) is set to the size in bytes
+**   (not characters) of the buffer and SQLITE_OK is returned. Otherwise,
+**   if an error occurs, an SQLite error code is returned and the final values
+**   of (*pz) and (*pn) are undefined.
+**
+** xPhraseCount:
+**   Returns the number of phrases in the current query expression.
+**
+** xPhraseSize:
+**   Returns the number of tokens in phrase iPhrase of the query. Phrases
+**   are numbered starting from zero.
+**
+** xInstCount:
+**   Set *pnInst to the total number of occurrences of all phrases within
+**   the query within the current row. Return SQLITE_OK if successful, or
+**   an error code (i.e. SQLITE_NOMEM) if an error occurs.
+**
+**   This API can be quite slow if used with an FTS5 table created with the
+**   "detail=none" or "detail=column" option. If the FTS5 table is created 
+**   with either "detail=none" or "detail=column" and "content=" option 
+**   (i.e. if it is a contentless table), then this API always returns 0.
+**
+** xInst:
+**   Query for the details of phrase match iIdx within the current row.
+**   Phrase matches are numbered starting from zero, so the iIdx argument
+**   should be greater than or equal to zero and smaller than the value
+**   output by xInstCount().
+**
+**   Usually, output parameter *piPhrase is set to the phrase number, *piCol
+**   to the column in which it occurs and *piOff the token offset of the
+**   first token of the phrase. Returns SQLITE_OK if successful, or an error
+**   code (i.e. SQLITE_NOMEM) if an error occurs.
+**
+**   This API can be quite slow if used with an FTS5 table created with the
+**   "detail=none" or "detail=column" option. 
+**
+** xRowid:
+**   Returns the rowid of the current row.
+**
+** xTokenize:
+**   Tokenize text using the tokenizer belonging to the FTS5 table.
+**
+** xQueryPhrase(pFts5, iPhrase, pUserData, xCallback):
+**   This API function is used to query the FTS table for phrase iPhrase
+**   of the current query. Specifically, a query equivalent to:
+**
+**       ... FROM ftstable WHERE ftstable MATCH $p ORDER BY rowid
+**
+**   with $p set to a phrase equivalent to the phrase iPhrase of the
+**   current query is executed. Any column filter that applies to
+**   phrase iPhrase of the current query is included in $p. For each 
+**   row visited, the callback function passed as the fourth argument 
+**   is invoked. The context and API objects passed to the callback 
+**   function may be used to access the properties of each matched row.
+**   Invoking Api.xUserData() returns a copy of the pointer passed as 
+**   the third argument to pUserData.
+**
+**   If the callback function returns any value other than SQLITE_OK, the
+**   query is abandoned and the xQueryPhrase function returns immediately.
+**   If the returned value is SQLITE_DONE, xQueryPhrase returns SQLITE_OK.
+**   Otherwise, the error code is propagated upwards.
+**
+**   If the query runs to completion without incident, SQLITE_OK is returned.
+**   Or, if some error occurs before the query completes or is aborted by
+**   the callback, an SQLite error code is returned.
+**
+**
+** xSetAuxdata(pFts5, pAux, xDelete)
+**
+**   Save the pointer passed as the second argument as the extension function's 
+**   "auxiliary data". The pointer may then be retrieved by the current or any
+**   future invocation of the same fts5 extension function made as part of
+**   the same MATCH query using the xGetAuxdata() API.
+**
+**   Each extension function is allocated a single auxiliary data slot for
+**   each FTS query (MATCH expression). If the extension function is invoked 
+**   more than once for a single FTS query, then all invocations share a 
+**   single auxiliary data context.
+**
+**   If there is already an auxiliary data pointer when this function is
+**   invoked, then it is replaced by the new pointer. If an xDelete callback
+**   was specified along with the original pointer, it is invoked at this
+**   point.
+**
+**   The xDelete callback, if one is specified, is also invoked on the
+**   auxiliary data pointer after the FTS5 query has finished.
+**
+**   If an error (e.g. an OOM condition) occurs within this function,
+**   the auxiliary data is set to NULL and an error code returned. If the
+**   xDelete parameter was not NULL, it is invoked on the auxiliary data
+**   pointer before returning.
+**
+**
+** xGetAuxdata(pFts5, bClear)
+**
+**   Returns the current auxiliary data pointer for the fts5 extension 
+**   function. See the xSetAuxdata() method for details.
+**
+**   If the bClear argument is non-zero, then the auxiliary data is cleared
+**   (set to NULL) before this function returns. In this case the xDelete,
+**   if any, is not invoked.
+**
+**
+** xRowCount(pFts5, pnRow)
+**
+**   This function is used to retrieve the total number of rows in the table.
+**   In other words, the same value that would be returned by:
+**
+**        SELECT count(*) FROM ftstable;
+**
+** xPhraseFirst()
+**   This function is used, along with type Fts5PhraseIter and the xPhraseNext
+**   method, to iterate through all instances of a single query phrase within
+**   the current row. This is the same information as is accessible via the
+**   xInstCount/xInst APIs. While the xInstCount/xInst APIs are more convenient
+**   to use, this API may be faster under some circumstances. To iterate 
+**   through instances of phrase iPhrase, use the following code:
+**
+**       Fts5PhraseIter iter;
+**       int iCol, iOff;
+**       for(pApi->xPhraseFirst(pFts, iPhrase, &iter, &iCol, &iOff);
+**           iCol>=0;
+**           pApi->xPhraseNext(pFts, &iter, &iCol, &iOff)
+**       ){
+**         // An instance of phrase iPhrase at offset iOff of column iCol
+**       }
+**
+**   The Fts5PhraseIter structure is defined above. Applications should not
+**   modify this structure directly - it should only be used as shown above
+**   with the xPhraseFirst() and xPhraseNext() API methods (and by
+**   xPhraseFirstColumn() and xPhraseNextColumn() as illustrated below).
+**
+**   This API can be quite slow if used with an FTS5 table created with the
+**   "detail=none" or "detail=column" option. If the FTS5 table is created 
+**   with either "detail=none" or "detail=column" and "content=" option 
+**   (i.e. if it is a contentless table), then this API always iterates
+**   through an empty set (all calls to xPhraseFirst() set iCol to -1).
+**
+** xPhraseNext()
+**   See xPhraseFirst above.
+**
+** xPhraseFirstColumn()
+**   This function and xPhraseNextColumn() are similar to the xPhraseFirst()
+**   and xPhraseNext() APIs described above. The difference is that instead
+**   of iterating through all instances of a phrase in the current row, these
+**   APIs are used to iterate through the set of columns in the current row
+**   that contain one or more instances of a specified phrase. For example:
+**
+**       Fts5PhraseIter iter;
+**       int iCol;
+**       for(pApi->xPhraseFirstColumn(pFts, iPhrase, &iter, &iCol);
+**           iCol>=0;
+**           pApi->xPhraseNextColumn(pFts, &iter, &iCol)
+**       ){
+**         // Column iCol contains at least one instance of phrase iPhrase
+**       }
+**
+**   This API can be quite slow if used with an FTS5 table created with the
+**   "detail=none" option. If the FTS5 table is created with either 
+**   "detail=none" "content=" option (i.e. if it is a contentless table), 
+**   then this API always iterates through an empty set (all calls to 
+**   xPhraseFirstColumn() set iCol to -1).
+**
+**   The information accessed using this API and its companion
+**   xPhraseFirstColumn() may also be obtained using xPhraseFirst/xPhraseNext
+**   (or xInst/xInstCount). The chief advantage of this API is that it is
+**   significantly more efficient than those alternatives when used with
+**   "detail=column" tables.  
+**
+** xPhraseNextColumn()
+**   See xPhraseFirstColumn above.

+** CUSTOM AUXILIARY FUNCTIONS
+*************************************************************************/
+
+/*************************************************************************
+** CUSTOM TOKENIZERS
+**
+** Applications may also register custom tokenizer types. A tokenizer 
+** is registered by providing fts5 with a populated instance of the 
+** following structure. All structure methods must be defined, setting
+** any member of the fts5_tokenizer struct to NULL leads to undefined
+** behaviour. The structure methods are expected to function as follows:
+**
+** xCreate:
+**   This function is used to allocate and initialize a tokenizer instance.
+**   A tokenizer instance is required to actually tokenize text.
+**
+**   The first argument passed to this function is a copy of the (void*)
+**   pointer provided by the application when the fts5_tokenizer object
+**   was registered with FTS5 (the third argument to xCreateTokenizer()). 
+**   The second and third arguments are an array of nul-terminated strings
+**   containing the tokenizer arguments, if any, specified following the
+**   tokenizer name as part of the CREATE VIRTUAL TABLE statement used
+**   to create the FTS5 table.
+**
+**   The final argument is an output variable. If successful, (*ppOut) 
+**   should be set to point to the new tokenizer handle and SQLITE_OK
+**   returned. If an error occurs, some value other than SQLITE_OK should
+**   be returned. In this case, fts5 assumes that the final value of *ppOut 
+**   is undefined.
+**
+** xDelete:
+**   This function is invoked to delete a tokenizer handle previously
+**   allocated using xCreate(). Fts5 guarantees that this function will
+**   be invoked exactly once for each successful call to xCreate().
+**
+** xTokenize:
+**   This function is expected to tokenize the nText byte string indicated 
+**   by argument pText. pText may or may not be nul-terminated. The first
+**   argument passed to this function is a pointer to an Fts5Tokenizer object
+**   returned by an earlier call to xCreate().
+**
+**   The second argument indicates the reason that FTS5 is requesting
+**   tokenization of the supplied text. This is always one of the following
+**   four values:
+**
+**   <ul><li> <b>FTS5_TOKENIZE_DOCUMENT</b> - A document is being inserted into
+**            or removed from the FTS table. The tokenizer is being invoked to
+**            determine the set of tokens to add to (or delete from) the
+**            FTS index.
+**
+**       <li> <b>FTS5_TOKENIZE_QUERY</b> - A MATCH query is being executed 
+**            against the FTS index. The tokenizer is being called to tokenize 
+**            a bareword or quoted string specified as part of the query.
+**
+**       <li> <b>(FTS5_TOKENIZE_QUERY | FTS5_TOKENIZE_PREFIX)</b> - Same as
+**            FTS5_TOKENIZE_QUERY, except that the bareword or quoted string is
+**            followed by a "*" character, indicating that the last token
+**            returned by the tokenizer will be treated as a token prefix.
+**
+**       <li> <b>FTS5_TOKENIZE_AUX</b> - The tokenizer is being invoked to 
+**            satisfy an fts5_api.xTokenize() request made by an auxiliary
+**            function. Or an fts5_api.xColumnSize() request made by the same
+**            on a columnsize=0 database.  
+**   </ul>
+**
+**   For each token in the input string, the supplied callback xToken() must
+**   be invoked. The first argument to it should be a copy of the pointer
+**   passed as the second argument to xTokenize(). The third and fourth
+**   arguments are a pointer to a buffer containing the token text, and the
+**   size of the token in bytes. The 4th and 5th arguments are the byte offsets
+**   of the first byte of and first byte immediately following the text from
+**   which the token is derived within the input.
+**
+**   The second argument passed to the xToken() callback ("tflags") should
+**   normally be set to 0. The exception is if the tokenizer supports 
+**   synonyms. In this case see the discussion below for details.
+**
+**   FTS5 assumes the xToken() callback is invoked for each token in the 
+**   order that they occur within the input text.
+**
+**   If an xToken() callback returns any value other than SQLITE_OK, then
+**   the tokenization should be abandoned and the xTokenize() method should
+**   immediately return a copy of the xToken() return value. Or, if the
+**   input buffer is exhausted, xTokenize() should return SQLITE_OK. Finally,
+**   if an error occurs with the xTokenize() implementation itself, it
+**   may abandon the tokenization and return any error code other than
+**   SQLITE_OK or SQLITE_DONE.
+**
+** SYNONYM SUPPORT
+**
+**   Custom tokenizers may also support synonyms. Consider a case in which a
+**   user wishes to query for a phrase such as "first place". Using the 
+**   built-in tokenizers, the FTS5 query 'first + place' will match instances
+**   of "first place" within the document set, but not alternative forms
+**   such as "1st place". In some applications, it would be better to match
+**   all instances of "first place" or "1st place" regardless of which form
+**   the user specified in the MATCH query text.
+**
+**   There are several ways to approach this in FTS5:
+**
+**   <ol><li> By mapping all synonyms to a single token. In this case, using
+**            the above example, this means that the tokenizer returns the
+**            same token for inputs "first" and "1st". Say that token is in
+**            fact "first", so that when the user inserts the document "I won
+**            1st place" entries are added to the index for tokens "i", "won",
+**            "first" and "place". If the user then queries for '1st + place',
+**            the tokenizer substitutes "first" for "1st" and the query works
+**            as expected.
+**
+**       <li> By querying the index for all synonyms of each query term
+**            separately. In this case, when tokenizing query text, the
+**            tokenizer may provide multiple synonyms for a single term 
+**            within the document. FTS5 then queries the index for each 
+**            synonym individually. For example, faced with the query:
+**
+**   <codeblock>
+**     ... MATCH 'first place'</codeblock>
+**
+**            the tokenizer offers both "1st" and "first" as synonyms for the
+**            first token in the MATCH query and FTS5 effectively runs a query 
+**            similar to:
+**
+**   <codeblock>
+**     ... MATCH '(first OR 1st) place'</codeblock>
+**
+**            except that, for the purposes of auxiliary functions, the query
+**            still appears to contain just two phrases - "(first OR 1st)" 
+**            being treated as a single phrase.
+**
+**       <li> By adding multiple synonyms for a single term to the FTS index.
+**            Using this method, when tokenizing document text, the tokenizer
+**            provides multiple synonyms for each token. So that when a 
+**            document such as "I won first place" is tokenized, entries are
+**            added to the FTS index for "i", "won", "first", "1st" and
+**            "place".
+**
+**            This way, even if the tokenizer does not provide synonyms
+**            when tokenizing query text (it should not - to do so would be
+**            inefficient), it doesn't matter if the user queries for 
+**            'first + place' or '1st + place', as there are entries in the
+**            FTS index corresponding to both forms of the first token.
+**   </ol>
+**
+**   Whether it is parsing document or query text, any call to xToken that
+**   specifies a <i>tflags</i> argument with the FTS5_TOKEN_COLOCATED bit
+**   is considered to supply a synonym for the previous token. For example,
+**   when parsing the document "I won first place", a tokenizer that supports
+**   synonyms would call xToken() 5 times, as follows:
+**
+**   <codeblock>
+**       xToken(pCtx, 0, "i",                      1,  0,  1);
+**       xToken(pCtx, 0, "won",                    3,  2,  5);
+**       xToken(pCtx, 0, "first",                  5,  6, 11);
+**       xToken(pCtx, FTS5_TOKEN_COLOCATED, "1st", 3,  6, 11);
+**       xToken(pCtx, 0, "place",                  5, 12, 17);
+**</codeblock>
+**
+**   It is an error to specify the FTS5_TOKEN_COLOCATED flag the first time
+**   xToken() is called. Multiple synonyms may be specified for a single token
+**   by making multiple calls to xToken(FTS5_TOKEN_COLOCATED) in sequence. 
+**   There is no limit to the number of synonyms that may be provided for a
+**   single token.
+**
+**   In many cases, method (1) above is the best approach. It does not add 
+**   extra data to the FTS index or require FTS5 to query for multiple terms,
+**   so it is efficient in terms of disk space and query speed. However, it
+**   does not support prefix queries very well. If, as suggested above, the
+**   token "first" is substituted for "1st" by the tokenizer, then the query:
+**
+**   <codeblock>
+**     ... MATCH '1s*'</codeblock>
+**
+**   will not match documents that contain the token "1st" (as the tokenizer
+**   will probably not map "1s" to any prefix of "first").
+**
+**   For full prefix support, method (3) may be preferred. In this case, 
+**   because the index contains entries for both "first" and "1st", prefix
+**   queries such as 'fi*' or '1s*' will match correctly. However, because
+**   extra entries are added to the FTS index, this method uses more space
+**   within the database.
+**
+**   Method (2) offers a midpoint between (1) and (3). Using this method,
+**   a query such as '1s*' will match documents that contain the literal 
+**   token "1st", but not "first" (assuming the tokenizer is not able to
+**   provide synonyms for prefixes). However, a non-prefix query like '1st'
+**   will match against "1st" and "first". This method does not require
+**   extra disk space, as no extra entries are added to the FTS index. 
+**   On the other hand, it may require more CPU cycles to run MATCH queries,
+**   as separate queries of the FTS index are required for each synonym.
+**
+**   When using methods (2) or (3), it is important that the tokenizer only
+**   provide synonyms when tokenizing document text (method (2)) or query
+**   text (method (3)), not both. Doing so will not cause any errors, but is
+**   inefficient.

Subject: [PATCH 015/276] [ffigen] Name conflict resolution with reserved Dart
 Keywords (#34)

Closes #21.

- Added reserved keyword conflict resolution to `UniqueNamer`.
- Added tests (`collision_tests/reserved_word_collision_test.dart`)
- Bug fix: UniqueNamers used by declarations are now reset to initial state before generating code. This ensures multiple calls to Library.generate will produce the same results

Subject: [PATCH 016/276] [ffigen] Prepare for pub release (#36)

- Updated version, changelog, readme, tests
- Dynamic library is now created at `.dart_tool/ffigen` in user's project.
- Added `bin/setup.dart` to load dynamic library (custom header/lib includes can be specified using `-I` / `-L` respectively.
- Generated classes for enums are now abstract.

+- HeaderFilter - Include/Exclude declarations from specific header files using name matching.
 - Filters - Include/Exclude function, structs and enum declarations using Regexp or Name matching.
+- Prefixing - function, structs and enums can have a global prefix. Individual prefix Replacement support using Regexp.
+- Comment extraction: full/brief/none
+- Support for fixed size arrays in struct. `array-workaround` (if enabled) will generate helpers for accessing fixed size arrays in structs.
+- Size for ints can be specified using `size-map` in config.
+- Options to disable using supported typedefs (e.g `uint8_t => Uint8`), sort bindings.
+- Option to add a raw `preamble` which is included as is in the generated file.

 # Libclang example
 
 Demonstrates generating bindings for [Libclang](https://clang.llvm.org/doxygen/group__CINDEX.html).
-This example actually uses a C file used in this package itself, ([wrapper.c](../../tool/wrapped_libclang/wrapper.c)), which adds a few more wrapper functions atop Libclang.
+The C header source files for libclang are in [third_party/libclang](/third_party/libclang).
 
 ## Generating bindings

Subject: [PATCH 018/276] [ffigen] Fixed wrapper not found error when running
 pub run ffigen (#42)

Possibly fixes #41 (Needs to be tested after publishing).

- Using `dart:cli` to resolve package uri and get wrapper.c for running `pub run ffigen:setup`.
- If `dart:cli` is unavailable, fallback tries to work up the current directory to find `.dart_tool/package_config.json` and get rootUri of `package:ffigen` and find wrapper.c from there.

Subject: [PATCH 021/276] [ffigen] Update config specification for Comments
 (#48)

Closes #38
- Comments config now has a style and length sub keys - `style: doxygen(default) | any`, `length: brief | full(default)`, and can be disabled by passing `comments: false`.
- Updated comment type in config.
- Updated readme to use `code` tag inside `pre` tag in config options.

+  /// <b>Callback Invocation Details</b>
+  ///
+  /// When an unlock-notify callback is registered, the application provides a

+  /// However, the signature of the callback function allows SQLite to pass
+  /// it an array of void* context pointers. The first argument passed to
+  /// an unlock-notify callback is a pointer to an array of void* pointers,
+  /// and the second is the number of entries in the array.
+  ///
+  /// When a blocking connection's transaction is concluded, there may be
+  /// more than one blocked connection that has registered for an unlock-notify
+  /// callback. ^If two or more such blocked connections have specified the
+  /// same callback function, then instead of invoking the callback function
+  /// multiple times, it is invoked once with the set of void* context pointers
+  /// specified by the blocked connections bundled together into an array.
+  /// This gives the application an opportunity to prioritize any actions
+  /// related to the set of unblocked database connections.
+  ///
+  /// <b>Deadlock Detection</b>
+  ///
+  /// Assuming that after registering for an unlock-notify callback a
+  /// database waits for the callback to be issued before taking any further
+  /// action (a reasonable assumption), then using this API may cause the
+  /// application to deadlock. For example, if connection X is waiting for
+  /// connection Y's transaction to be concluded, and similarly connection
+  /// Y is waiting on connection X's transaction, then neither connection
+  /// will proceed and the system may remain deadlocked indefinitely.
+  ///
+  /// To avoid this scenario, the sqlite3_unlock_notify() performs deadlock
+  /// detection. ^If a given call to sqlite3_unlock_notify() would put the
+  /// system in a deadlocked state, then SQLITE_LOCKED is returned and no
+  /// unlock-notify callback is registered. The system is said to be in
+  /// a deadlocked state if connection A has registered for an unlock-notify
+  /// callback on the conclusion of connection B's transaction, and connection
+  /// B has itself registered for an unlock-notify callback when connection
+  /// A's transaction is concluded. ^Indirect deadlock is also detected, so
+  /// the system is also considered to be deadlocked if connection B has
+  /// registered for an unlock-notify callback on the conclusion of connection
+  /// C's transaction, where connection C is waiting on connection A. ^Any
+  /// number of levels of indirection are allowed.
+  ///
+  /// <b>The "DROP TABLE" Exception</b>
+  ///
+  /// When a call to [sqlite3_step()] returns SQLITE_LOCKED, it is almost
+  /// always appropriate to call sqlite3_unlock_notify(). There is however,
+  /// one exception. When executing a "DROP TABLE" or "DROP INDEX" statement,
+  /// SQLite checks if there are any currently executing SELECT statements
+  /// that belong to the same connection. If there are, SQLITE_LOCKED is
+  /// returned. In this case there is no "blocking connection", so invoking
+  /// sqlite3_unlock_notify() results in the unlock-notify callback being

+/// relevant to the particular virtual table being queried.
+///
+/// ^Information about the ORDER BY clause is stored in aOrderBy[].
+/// ^Each term of aOrderBy records a column of the ORDER BY clause.
+///
+/// The colUsed field indicates which columns of the virtual table may be

+/// passed to sqlite3_declare_vtab(). For the first 63 columns (columns 0-62),

+/// ^The orderByConsumed means that output from [xFilter]/[xNext] will occur in

+/// sorting step is required.
+///
+/// ^The estimatedCost value is an estimate of the cost of a particular
+/// strategy. A cost of N indicates that the cost of the strategy is similar
+/// to a linear scan of an SQLite table with N rows. A cost of log(N)
+/// indicates that the expense of the operation is similar to that of a
+/// binary search on a unique indexed field of an SQLite table with N rows.
+///
+/// ^The estimatedRows value is an estimate of the number of rows that
+/// will be returned by the strategy.
+///
+/// The xBestIndex method may optionally populate the idxFlags field with a
+/// mask of SQLITE_INDEX_SCAN_* flags. Currently there is only one such flag -
+/// SQLITE_INDEX_SCAN_UNIQUE. If the xBestIndex method sets this flag, SQLite
+/// assumes that the strategy may visit at most one row.
+///
+/// Additionally, if xBestIndex sets the SQLITE_INDEX_SCAN_UNIQUE flag, then
+/// SQLite also assumes that if a call to the xUpdate() method is made as
+/// part of the same statement to delete or update a virtual table row and the
+/// implementation returns SQLITE_CONSTRAINT, then there is no need to rollback
+/// any database changes. In other words, if the xUpdate() returns
+/// SQLITE_CONSTRAINT, the database contents must be exactly as they were
+/// before xUpdate was called. By contrast, if SQLITE_INDEX_SCAN_UNIQUE is not
+/// set and xUpdate returns SQLITE_CONSTRAINT, any database changes made by
+/// the xUpdate method are automatically rolled back by SQLite.
+///

+/// EXTENSION API FUNCTIONS
+///
+/// xUserData(pFts):
+/// Return a copy of the context pointer the extension function was
+/// registered with.
+///
+/// xColumnTotalSize(pFts, iCol, pnToken):
+/// If parameter iCol is less than zero, set output variable *pnToken
+/// to the total number of tokens in the FTS5 table. Or, if iCol is
+/// non-negative but less than the number of columns in the table, return
+/// the total number of tokens in column iCol, considering all rows in
+/// the FTS5 table.
+///
+/// If parameter iCol is greater than or equal to the number of columns
+/// in the table, SQLITE_RANGE is returned. Or, if an error occurs (e.g.
+/// an OOM condition or IO error), an appropriate SQLite error code is
+/// returned.
+///
+/// xColumnCount(pFts):
+/// Return the number of columns in the table.
+///
+/// xColumnSize(pFts, iCol, pnToken):
+/// If parameter iCol is less than zero, set output variable *pnToken
+/// to the total number of tokens in the current row. Or, if iCol is
+/// non-negative but less than the number of columns in the table, set
+/// *pnToken to the number of tokens in column iCol of the current row.
+///
+/// If parameter iCol is greater than or equal to the number of columns
+/// in the table, SQLITE_RANGE is returned. Or, if an error occurs (e.g.
+/// an OOM condition or IO error), an appropriate SQLite error code is
+/// returned.
+///
+/// This function may be quite inefficient if used with an FTS5 table
+/// created with the "columnsize=0" option.
+///
+/// xColumnText:
+/// This function attempts to retrieve the text of column iCol of the
+/// current document. If successful, (*pz) is set to point to a buffer
+/// containing the text in utf-8 encoding, (*pn) is set to the size in bytes
+/// (not characters) of the buffer and SQLITE_OK is returned. Otherwise,
+/// if an error occurs, an SQLite error code is returned and the final values
+/// of (*pz) and (*pn) are undefined.
+///
+/// xPhraseCount:
+/// Returns the number of phrases in the current query expression.
+///
+/// xPhraseSize:
+/// Returns the number of tokens in phrase iPhrase of the query. Phrases
+/// are numbered starting from zero.
+///
+/// xInstCount:
+/// Set *pnInst to the total number of occurrences of all phrases within
+/// the query within the current row. Return SQLITE_OK if successful, or
+/// an error code (i.e. SQLITE_NOMEM) if an error occurs.
+///
+/// This API can be quite slow if used with an FTS5 table created with the
+/// "detail=none" or "detail=column" option. If the FTS5 table is created
+/// with either "detail=none" or "detail=column" and "content=" option
+/// (i.e. if it is a contentless table), then this API always returns 0.
+///
+/// xInst:
+/// Query for the details of phrase match iIdx within the current row.
+/// Phrase matches are numbered starting from zero, so the iIdx argument
+/// should be greater than or equal to zero and smaller than the value
+/// output by xInstCount().
+///
+/// Usually, output parameter *piPhrase is set to the phrase number, *piCol
+/// to the column in which it occurs and *piOff the token offset of the
+/// first token of the phrase. Returns SQLITE_OK if successful, or an error
+/// code (i.e. SQLITE_NOMEM) if an error occurs.
+///
+/// This API can be quite slow if used with an FTS5 table created with the
+/// "detail=none" or "detail=column" option.
+///
+/// xRowid:
+/// Returns the rowid of the current row.
+///
+/// xTokenize:
+/// Tokenize text using the tokenizer belonging to the FTS5 table.
+///
+/// xQueryPhrase(pFts5, iPhrase, pUserData, xCallback):
+/// This API function is used to query the FTS table for phrase iPhrase
+/// of the current query. Specifically, a query equivalent to:
+///
+/// ... FROM ftstable WHERE ftstable MATCH $p ORDER BY rowid
+///
+/// with $p set to a phrase equivalent to the phrase iPhrase of the
+/// current query is executed. Any column filter that applies to
+/// phrase iPhrase of the current query is included in $p. For each
+/// row visited, the callback function passed as the fourth argument
+/// is invoked. The context and API objects passed to the callback
+/// function may be used to access the properties of each matched row.
+/// Invoking Api.xUserData() returns a copy of the pointer passed as
+/// the third argument to pUserData.
+///
+/// If the callback function returns any value other than SQLITE_OK, the
+/// query is abandoned and the xQueryPhrase function returns immediately.
+/// If the returned value is SQLITE_DONE, xQueryPhrase returns SQLITE_OK.
+/// Otherwise, the error code is propagated upwards.
+///
+/// If the query runs to completion without incident, SQLITE_OK is returned.
+/// Or, if some error occurs before the query completes or is aborted by
+/// the callback, an SQLite error code is returned.
+///
+///
+/// xSetAuxdata(pFts5, pAux, xDelete)
+///
+/// Save the pointer passed as the second argument as the extension function's
+/// "auxiliary data". The pointer may then be retrieved by the current or any
+/// future invocation of the same fts5 extension function made as part of
+/// the same MATCH query using the xGetAuxdata() API.
+///
+/// Each extension function is allocated a single auxiliary data slot for
+/// each FTS query (MATCH expression). If the extension function is invoked
+/// more than once for a single FTS query, then all invocations share a
+/// single auxiliary data context.
+///
+/// If there is already an auxiliary data pointer when this function is
+/// invoked, then it is replaced by the new pointer. If an xDelete callback
+/// was specified along with the original pointer, it is invoked at this
+/// point.
+///
+/// The xDelete callback, if one is specified, is also invoked on the
+/// auxiliary data pointer after the FTS5 query has finished.
+///
+/// If an error (e.g. an OOM condition) occurs within this function,
+/// the auxiliary data is set to NULL and an error code returned. If the
+/// xDelete parameter was not NULL, it is invoked on the auxiliary data
+/// pointer before returning.
+///
+///
+/// xGetAuxdata(pFts5, bClear)
+///
+/// Returns the current auxiliary data pointer for the fts5 extension
+/// function. See the xSetAuxdata() method for details.
+///
+/// If the bClear argument is non-zero, then the auxiliary data is cleared
+/// (set to NULL) before this function returns. In this case the xDelete,
+/// if any, is not invoked.
+///
+///
+/// xRowCount(pFts5, pnRow)
+///
+/// This function is used to retrieve the total number of rows in the table.
+/// In other words, the same value that would be returned by:
+///
+/// SELECT count(*) FROM ftstable;
+///
+/// xPhraseFirst()
+/// This function is used, along with type Fts5PhraseIter and the xPhraseNext
+/// method, to iterate through all instances of a single query phrase within
+/// the current row. This is the same information as is accessible via the
+/// xInstCount/xInst APIs. While the xInstCount/xInst APIs are more convenient
+/// to use, this API may be faster under some circumstances. To iterate
+/// through instances of phrase iPhrase, use the following code:
+///
+/// Fts5PhraseIter iter;
+/// int iCol, iOff;
+/// for(pApi->xPhraseFirst(pFts, iPhrase, &iter, &iCol, &iOff);
+/// iCol>=0;
+/// pApi->xPhraseNext(pFts, &iter, &iCol, &iOff)
+/// ){
+/// // An instance of phrase iPhrase at offset iOff of column iCol
+/// }
+///
+/// The Fts5PhraseIter structure is defined above. Applications should not
+/// modify this structure directly - it should only be used as shown above
+/// with the xPhraseFirst() and xPhraseNext() API methods (and by
+/// xPhraseFirstColumn() and xPhraseNextColumn() as illustrated below).
+///
+/// This API can be quite slow if used with an FTS5 table created with the
+/// "detail=none" or "detail=column" option. If the FTS5 table is created
+/// with either "detail=none" or "detail=column" and "content=" option
+/// (i.e. if it is a contentless table), then this API always iterates
+/// through an empty set (all calls to xPhraseFirst() set iCol to -1).
+///
+/// xPhraseNext()
+/// See xPhraseFirst above.
+///
+/// xPhraseFirstColumn()
+/// This function and xPhraseNextColumn() are similar to the xPhraseFirst()
+/// and xPhraseNext() APIs described above. The difference is that instead
+/// of iterating through all instances of a phrase in the current row, these
+/// APIs are used to iterate through the set of columns in the current row
+/// that contain one or more instances of a specified phrase. For example:
+///
+/// Fts5PhraseIter iter;
+/// int iCol;
+/// for(pApi->xPhraseFirstColumn(pFts, iPhrase, &iter, &iCol);
+/// iCol>=0;
+/// pApi->xPhraseNextColumn(pFts, &iter, &iCol)
+/// ){
+/// // Column iCol contains at least one instance of phrase iPhrase
+/// }
+///
+/// This API can be quite slow if used with an FTS5 table created with the
+/// "detail=none" option. If the FTS5 table is created with either
+/// "detail=none" "content=" option (i.e. if it is a contentless table),
+/// then this API always iterates through an empty set (all calls to
+/// xPhraseFirstColumn() set iCol to -1).
+///
+/// The information accessed using this API and its companion
+/// xPhraseFirstColumn() may also be obtained using xPhraseFirst/xPhraseNext
+/// (or xInst/xInstCount). The chief advantage of this API is that it is
+/// significantly more efficient than those alternatives when used with
+/// "detail=column" tables.
+///
+/// xPhraseNextColumn()
+/// See xPhraseFirstColumn above.

Subject: [PATCH 023/276] [ffigen] Update headers config. (#60)

Closes #52
- Updated headers config to have sub-fields `entry-points` and `include-directives`, removed `header-filter` config.
- Globs are supported by both subkeys.
- Updated tests, examples, readme, changelog.

Subject: [PATCH 025/276] [ffigen] Simpler include/exclude, regexp based
 renaming for declarations (#62)

* Removes names/matches from include/exclude. Updated examples. Removed typedef incremental renaming.

* restored incremental typedef naming using IncrementalNamer, (this improves UniqueNamer's performance because there are less clashes

* added declaration renaming

* minor changes

* updated readme, changelog

* readme fix

* added to changelog

* simplified declaration using includer and renamer

* Includer: replaced firstMatch and end comparision with quiver.matchesFull

 # 0.2.0-dev
 - Updated header config. Header `entry-points` and `include-directives` are now specified under `headers` key. Glob syntax is allowed.
+- Updated declaration `include`/`exclude` config. These are now specified as a list.
+- Added Regexp based declaration renaming using `rename` subkey.
 
 # 0.1.5
 - Added support for parsing macros and anonymous unnamed enums. These are generated as top level constants.

 - Updated header config. Header `entry-points` and `include-directives` are now specified under `headers` key. Glob syntax is allowed.
 - Updated declaration `include`/`exclude` config. These are now specified as a list.
 - Added Regexp based declaration renaming using `rename` subkey.
+- Added Regexp based member renaming for structs, enums and functions using `member-rename` subkey. `prefix` and `prefix-replacement` subkeys have been removed.
 
 # 0.1.5
 - Added support for parsing macros and anonymous unnamed enums. These are generated as top level constants.

Subject: [PATCH 028/276] [ffigen] Update public API (#70)

- Updated `Config`'s class members to use public getter, private variable pattern.
- Replaced ConfigError with FormatException.
- Refactored all shared global variables to data.dart.
- Send test coverage to coveralls in travis.

+          the Derivative Works; and
+
+      (d) If the Work includes a "NOTICE" text file as part of its
+          distribution, then any Derivative Works that You distribute must
+          include a readable copy of the attribution notices contained
+          within such NOTICE file, excluding those notices that do not
+          pertain to any part of the Derivative Works, in at least one
+          of the following places: within a NOTICE text file distributed
+          as part of the Derivative Works; within the Source form or
+          documentation, if provided along with the Derivative Works; or,

+          wherever such third-party notices normally appear. The contents
+          of the NOTICE file are for informational purposes only and
+          do not modify the License. You may add Your own attribution
+          notices within Derivative Works that You distribute, alongside
+          or as an addendum to the NOTICE text from the Work, provided
+          that such additional attribution notices cannot be construed
+          as modifying the License.
+
+      You may add Your own copyright statement to Your modifications and
+      may provide additional or different license terms and conditions
+      for use, reproduction, or distribution of Your modifications, or
+      for any such Derivative Works as a whole, provided Your use,
+      reproduction, and distribution of the Work otherwise complies with
+      the conditions stated in this License.
+
+    5. Submission of Contributions. Unless You explicitly state otherwise,
+      any Contribution intentionally submitted for inclusion in the Work
+      by You to the Licensor shall be under the terms and conditions of
+      this License, without any additional terms or conditions.
+      Notwithstanding the above, nothing herein shall supersede or modify
+      the terms of any separate license agreement you may have executed
+      with Licensor regarding such Contributions.
+
+    6. Trademarks. This License does not grant permission to use the trade
+      names, trademarks, service marks, or product names of the Licensor,
+      except as required for reasonable and customary use in describing the
+      origin of the Work and reproducing the content of the NOTICE file.
+
+    7. Disclaimer of Warranty. Unless required by applicable law or
+      agreed to in writing, Licensor provides the Work (and each
+      Contributor provides its Contributions) on an "AS IS" BASIS,
+      WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or
+      implied, including, without limitation, any warranties or conditions
+      of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A
+      PARTICULAR PURPOSE. You are solely responsible for determining the
+      appropriateness of using or redistributing the Work and assume any
+      risks associated with Your exercise of permissions under this License.
+
+    8. Limitation of Liability. In no event and under no legal theory,
+      whether in tort (including negligence), contract, or otherwise,
+      unless required by applicable law (such as deliberate and grossly
+      negligent acts) or agreed to in writing, shall any Contributor be
+      liable to You for damages, including any direct, indirect, special,
+      incidental, or consequential damages of any character arising as a
+      result of this License or out of the use or inability to use the
+      Work (including but not limited to damages for loss of goodwill,
+      work stoppage, computer failure or malfunction, or any and all
+      other commercial damages or losses), even if such Contributor
+      has been advised of the possibility of such damages.
+
+    9. Accepting Warranty or Additional Liability. While redistributing
+      the Work or Derivative Works thereof, You may choose to offer,
+      and charge a fee for, acceptance of support, warranty, indemnity,
+      or other liability obligations and/or rights consistent with this
+      License. However, in accepting such obligations, You may act only
+      on Your own behalf and on Your sole responsibility, not on behalf
+      of any other Contributor, and only if You agree to indemnify,
+      defend, and hold each Contributor harmless for any liability
+      incurred by, or claims asserted against, such Contributor by reason
+      of your accepting any such warranty or additional liability.

+## FAQ
+### Can ffigen be used for removing underscores or renaming declarations?
+Ffigen supports **regexp based renaming**, the regexp must be a
+full match, for renaming you can use regexp groups (`$1` means group 1).
+
+E.g - For renaming `clang_dispose_string` to `string_dispose`.
+We can can match it using `clang_(.*)_(.*)` and rename with `$2_$1`.
+
+Here's an example of how to remove prefix underscores from any struct and its members.
+```yaml
+structs:
+  ...
+  rename:
+    '_(.*)': '$1' # Removes prefix underscores from all structures.
+  member-rename:
+    '.*': # Matches any struct.
+      '_(.*)': '$1' # Removes prefix underscores from members.
+```
+### How to generate declarations only from particular headers?
+The default behaviour is to include everything directly/transitively under
+each of the `entry-points` specified.
+
+If you only want to have declarations directly particular header you can do so
+using `include-directives`. You can use **glob matching** to match header paths.
+```yaml
+headers:
+  entry-points:
+    - 'path/to/my_header.h'
+  include-directives:
+    - '**my_header.h' # This glob pattern matches the header path.
+```
+### Can ffigen filter declarations by name?
+Ffigen supports including/excluding declarations using full regexp matching.
+
+Here's an example to filter functions using names
+```yaml
+functions:
+  include:
+    - 'clang.*' # Include all functions starting with clang.
+  exclude:
+    - '.*dispose': # Exclude all functions ending with dispose.
+```
+This will include `clang_help`. But will exclude `clang_dispose`.
+
+Note: exclude overrides include.
+### How does ffigen handle C Strings?
+
+Ffigen treats `char*` just as any other pointer,(`Pointer<Int8>`).
+To convert these to/from `String`, you can use [package:ffi](https://pub.dev/packages/ffi) and use `Utf8.fromUtf8(ptr.cast())` to convert `char*` to dart `string`.

Subject: [PATCH 032/276] [ffigen] Updated parsing of typedef enclosed
 declarations (#83)

* added getCursorUSR_wrap method to wrapper, and bindings

* Updated code to use libclang's USR for identification

* Struct's typedef name will be used now (if it is only used in 1 typedef)

* parseXXX now returns seen binding instead of null

* added tests and removed obsolete code

* updated version, changelog, test_coverage.dart

* added PR ref to changelog

* minor changes

Subject: [PATCH 036/276] [ffigen] Improve logs (#87)

* Added fallback to flutter format if dartfmt is not found

* added red color for severe, green for success in log printing

* Only catch ProcessException when calling dartfmt

* used package:cli_utils for finding dart_sdk and ansi colors

* use path.join

Subject: [PATCH 038/276] [ffigen] Added support for c99 bool (#86)

* Bool datatype is now mapped to Uint8, Added test in native_test

* Added dart-bool to config, bools in function parameters and return type now use dart bool instead of int by default

 Ffigen treats `char*` just as any other pointer,(`Pointer<Int8>`).
 To convert these to/from `String`, you can use [package:ffi](https://pub.dev/packages/ffi) and use `Utf8.fromUtf8(ptr.cast())` to convert `char*` to dart `string`.
+### How does ffigen handle C99 bool data type?
+
+Although `dart:ffi` doesn't have a NativeType for `bool`, they can be implemented as `Uint8`.
+Ffigen generates dart `bool` for function parameters and return type by default.
+To disable this, and use `int` instead, set `dart-bool: false` in configurations.

 Although `dart:ffi` doesn't have a NativeType for `bool`, they can be implemented as `Uint8`.
 Ffigen generates dart `bool` for function parameters and return type by default.
 To disable this, and use `int` instead, set `dart-bool: false` in configurations.
+
+### How are unnamed enums handled?
+
+Unnamed enums are handled separately, under the key `unnamed-enums`, and are generated as top level constants.
+
+Here's an example that shows how to include/exclude/rename unnamed enums
+```yaml
+unnamed-enums:
+  include:
+    - 'CX_.*'
+  exclude:
+    - '.*Flag'
+  rename:
+    'CXType_(.*)': '$1'
+```
+
+### Why are some struct declarations generated even after excluded them in config?
+
+This happens when an excluded struct is a dependency to some included declaration.
+(A dependency means a struct is being passed/returned by a function or is member of another struct in some way)

+# Overview
+`package:ffigen` simplifies the process of generating `dart:ffi` bindings from C header files. It is simple to use, with the input being a small YAML config file. It requires LLVM (9+) to work. This document tries to give a complete overview of every component without going into too many details about every single class/file.
+# LibClang
+`package:ffigen` binds to LibClang using `dart:ffi` for parsing C header files. A wrapper library must be generated to use it, as `dart:ffi` currently [doesn't support structs by value](https://github.com/dart-lang/ffigen/issues/3).
+## The Wrapper library
+> Note: The wrapper is only needed because `dart:ffi` currently doesn't support Structs by value.
 
-- `bin` - Contains ffigen.dart script which end user will execute.
-- `tool` - Contains script to generate LibClang bindings using Code_Generator submodule (dev use only).
-- `example` - Example projects which demonstrate generation of bindings for given C header files.
-- `lib/src/code_generator` - Generates binding files.
-- `lib/src/config_provider` - Holds configurations to be passed to other modules.
-- `lib/src/header_parser` - Parses header files, utilises clang_bindings.
+The `wrapper.c` file consists of functions that wrap LibClang functions. Most of them simply convert structs by value to pointers. Except -
+- `clang_visitChildren_wrap` - The bindings for this function internally uses a **list** of **stack** for maintaining the supplied visitor functions. This is required because this function takes a function pointer which itself passes a struct by value. All this effort makes `clang_visitChildren_wrap` behave exactly like `clang_visitChildren`.
+## Generation and Usage
+The files needed for generating the wrapper are in `lib/src/clang_library`.
+> The `wrapper.def` file is only needed on windows because the symbols are otherwise hidden.
 
-## Basic Workflow
-1. The User provides the location all the header files (as a list of globs or filepaths),
-For each header file, we create a translation unit and parse the `declarations` in it
-to the bindings.
-2. User can provide `header filters` to select which declaration from a particular header file should be added to the generated bindings. The can provide a list of header 'names' to include/exclude.
-We compare the header file name (not the exact path) to decide.
-The default behaviour is to include everything that's included when parsing a header.
-3. Use can provide Compiler options, which are passed to clang compiler as it is.
-4. All bindings are generated in a single file.
+The libclang wrapper can be _manually_ generated using `pub run ffigen:setup`. See [setup.dart](#setup.dart) for details.
 
-# Code Details
-## Modules
-We are using libclang to parse header files.
-This project is roughly divided in 3 major modules -
-### code_generator
-Converts a library(all bindings) to an actual string representation.
-- Library (output of the header parser).
-- Writer (provides configurations for generating bindings).
-- Binding (base class for all bindings - Func, Struc, Global, EnumClass, etc).
-### config_provider
-This takes care of validating user config files, printing config warnings and errors,
-converting config.yaml to a format the header_parser can use.
-- Spec (represents a single config, which a user can provide in the config file).
-- Config (holds all the config which will be required by header parser).
-### header_parser
-Uses libclang to convert the header to a Library which is then used by code_generator.
-- clang_bindings (bindings to libclang which are used for parsing).
-- sub_parsers (each sub-parser parses a particular kind of declaration - struct, function, typedef, enum).
-- type_extractor (extracts types from variables, function parameters, return types).
-- includer (tells what should/shouldn't be included depending of config).
-- parser (Main Entrypoint) (creates translation units for all header files, and sets up parsing them).
-- translation_unit_parser (parses header files, splits declarations and feeds them to their respective sub_parsers).
+The generated file is placed in the project's `.dart_tool/ffigen` folder, the file name also specifies the ffigen version (E.g - `_v0_2_4_libclang_wrapper.dylib`), this helps ensure the correct wrapper is being used for its corresponding version.
+
+This dynamic library is then used by [Header Parser](#header-parser) for parsing C files.
+## Bindings
+The config file for generating bindings is `tool/libclang_config.yaml`. The bindings are generated to `lib/src/header_parser/clang_bindings/clang_bindings.dart`. These are used by [Header Parser](#header-parser) for calling libclang functions.
+# Scripts
+## ffigen.dart
+This is the main entry point for the user-  `pub run ffigen`.
+- Command-line options:
+    - `--verbose`: Sets log level.
+    - `--config`: Specifies a config file.
+- `ffigen.dart` will first check if a dynamic library already exists and is up to date. If not, it tries to auto-create it. If that fails, user must excplicitly call [setup.dart](#setup.dart).
+- The internal modules are called by `ffigen.dart` in the following way:
+    - It first creates a `Config` object from an input Yaml file. This is used by other modules.
+    - The `parse` method is then invoked to generate a `Library` object.
+    - Finally, the code is generated from the `Library` object to the specified file.
+## setup.dart
+Used to generate the wrapper dynamic library. Users will need to explicitly call this if `pub run ffigen` is unable to auto-create the dynamic library.
+> `clang` must be on user's path for `setup.dart` to work.
+
+- Command-line options:
+    - `-I`: Specifies header includes.
+    - `-L`: Specifies library includes.
+- `setup.dart` generates the dynamic library to the project's `.dart_tool/ffigen` folder using `clang`.
+# Components
+## Config Provider
+The Config Provider holds all the configurations required by other modules.
+- Config Provider handles validation and extraction of configurations from YAML files.
+- Config Provider converts configurations to the format required by other modules. This object is passed around to every other module.
+## Header Parser
+The Header Parser parses C header files and converts them into a `Library` object.
+- Header Parser handles including/excluding/renaming of declarations.
+- Header Parser also filters out any _unimplemented_ or _unsupported_ declarations before generating a `Library` object.
+## Code Generator
+The Code Generator generates the actual string bindings.
+- Code generator handles all external name collisions, while internal name conflicts are handled by each specific `Binding`.
+- Code Generator also handles how workarounds for arrays and bools are generated.

 ## Limitations
 1. Multi OS support for types such as long. [Issue #7](https://github.com/dart-lang/ffigen/issues/7)
-2. Function's passing/returning structs by value are skipped. [Issue #3](https://github.com/dart-lang/ffigen/issues/3)
-3. Structs containing structs will have all their members removed. [Issue #4](https://github.com/dart-lang/ffigen/issues/4)
 
 ## Trying out examples
 1. `cd examples/<example_u_want_to_run>`, Run `pub get`.

-  /// "p" points to. The client is responsible for placing the cursor at the
-  /// beginning of the token currently being typed, then filtering the results
-  /// based on the contents of the token. For example, when code-completing for
-  /// the expression \c p->get, the client should provide the location just after
-  /// the ">" (e.g., pointing at the "g") to this code-completion hook. Then, the
-  /// client can filter the results based on the current token text ("get"), only
-  /// showing those results that start with "get". The intent of this interface

 # Overview
 `package:ffigen` simplifies the process of generating `dart:ffi` bindings from C header files. It is simple to use, with the input being a small YAML config file. It requires LLVM (9+) to work. This document tries to give a complete overview of every component without going into too many details about every single class/file.
 # LibClang
-`package:ffigen` binds to LibClang using `dart:ffi` for parsing C header files. A wrapper library must be generated to use it, as `dart:ffi` currently [doesn't support structs by value](https://github.com/dart-lang/ffigen/issues/3).
-## The Wrapper library
-> Note: The wrapper is only needed because `dart:ffi` currently doesn't support Structs by value.
-
-The `wrapper.c` file consists of functions that wrap LibClang functions. Most of them simply convert structs by value to pointers. Except -
-- `clang_visitChildren_wrap` - The bindings for this function internally uses a **list** of **stack** for maintaining the supplied visitor functions. This is required because this function takes a function pointer which itself passes a struct by value. All this effort makes `clang_visitChildren_wrap` behave exactly like `clang_visitChildren`.
-## Generation and Usage
-The files needed for generating the wrapper are in `lib/src/clang_library`.
-> The `wrapper.def` file is only needed on windows because the symbols are otherwise hidden.
-
-The libclang wrapper can be _manually_ generated using `pub run ffigen:setup`. See [setup.dart](#setup.dart) for details.
-
-The generated file is placed in the project's `.dart_tool/ffigen` folder, the file name also specifies the ffigen version (E.g - `_v0_2_4_libclang_wrapper.dylib`), this helps ensure the correct wrapper is being used for its corresponding version.
-
-This dynamic library is then used by [Header Parser](#header-parser) for parsing C files.
+`package:ffigen` binds to LibClang using `dart:ffi` for parsing C header files. 
 ## Bindings
 The config file for generating bindings is `tool/libclang_config.yaml`. The bindings are generated to `lib/src/header_parser/clang_bindings/clang_bindings.dart`. These are used by [Header Parser](#header-parser) for calling libclang functions.
 # Scripts
@@ -38,19 +21,11 @@ This is the main entry point for the user-  `pub run ffigen`.
 - Command-line options:
     - `--verbose`: Sets log level.
     - `--config`: Specifies a config file.
-- `ffigen.dart` will first check if a dynamic library already exists and is up to date. If not, it tries to auto-create it. If that fails, user must excplicitly call [setup.dart](#setup.dart).
 - The internal modules are called by `ffigen.dart` in the following way:
+- `ffigen.dart` will try to find dynamic library in default locations. If that fails, the user must excplicitly specify location in ffigen's config under the key `llvm-lib`.
     - It first creates a `Config` object from an input Yaml file. This is used by other modules.
     - The `parse` method is then invoked to generate a `Library` object.
     - Finally, the code is generated from the `Library` object to the specified file.
-## setup.dart
-Used to generate the wrapper dynamic library. Users will need to explicitly call this if `pub run ffigen` is unable to auto-create the dynamic library.
-> `clang` must be on user's path for `setup.dart` to work.
-
-- Command-line options:
-    - `-I`: Specifies header includes.
-    - `-L`: Specifies library includes.
-- `setup.dart` generates the dynamic library to the project's `.dart_tool/ffigen` folder using `clang`.
 # Components
 ## Config Provider
 The Config Provider holds all the configurations required by other modules.

Subject: [PATCH 065/276] [ffigen] Fixes for `const` in name error, unnamed
 inline structs and empty structs. (#169)

* Fix windows issues
* Added test for unnamed struct
* Fix error due to const function pointer in structs
* Mark empty struct as incomplete, mark struct with array of incomplete struct as incomplete.

 This happens when an excluded struct is a dependency to some included declaration.

+
+### How to expose the native pointers and typedefs?
+
+By default all native pointers and typedefs are hidden, but you can use the
+`symbol-address` subkey for functions/globals and make them public by matching with its name. The pointers are then accesible via `nativeLibrary.addresses` and the native
+typedef are prefixed with `Native_`.
+
+Example -
+```yaml
+functions:
+  symbol-address:
+    include:
+      - 'myFunc'
+      - '.*' # Do this to expose all pointers.
+```

+# 2.2.3
+- Added new subkey `dependency-only` (options - `full (default) | opaque`) under `structs`.
+When set to `opaque`, ffigen will generate empty `Opaque` structs if structs
+were excluded in config (i.e added because they were a dependency) and
+only passed by reference(pointer).

 # 2.2.2
 - Fixed generation of empty opaque structs due to forward declarations in header files.

-Fixed size array's in structs aren't currently supported by Dart. However we provide
-a workaround, using which array items can now be accessed using `[]` operator.

-typedef struct {
-  unsigned long long data[3];
-} CXFileUniqueID;

Subject: [PATCH 083/276] [ffigen] Update readme to clarify C support. (#209)

We will not support C++ headers, because C++ does not have a stable ABI like C (or use of extern "C" in C++ headers). Without a stable ABI it is impossible to know in what register/stack locations to pass arguments and this will lead to endless segmentation faults.

We could potentially support C++ headers which have extern "C" on every symbol, but we will not support C++ headers.

+### How are Structs/Unions/Enums that are reffered to via typedefs handled?
+
+Named declarations use their own names even when inside another typedef.
+However, unnamed declarations inside typedefs take the name of the _first_ typedef
+that refers to them.
+
+### Why are some typedefs not generated?
+
+The following typedefs are not generated -
+- They are not referred to anywhere in the included declarations.
+- They refer to a struct/union having the same name as itself.
+- They refer to a boolean, enum, inline array, Handle or any unsupported type.

-/// ^The registration remains valid until it is replaced by a different

+- This package now targets package:lints for the generated code. The generated
+code uses C symbol names as is. Use either `// ignore_for_file: lintRule1, lintRule2`
+in the `preamble`, or rename the symbols to make package:lints happy.
+- Name collisions are now resolved by suffixing `<int>` instead of `_<int>`.

 # 4.0.0-dev.0

 ### How to expose the native pointers and typedefs?
 
 By default all native pointers and typedefs are hidden, but you can use the
-`symbol-address` subkey for functions/globals and make them public by matching with its name. The pointers are then accesible via `nativeLibrary.addresses` and the native
-typedef are prefixed with `Native_`.

+- Config key `function`->`symbol-address` no longer exposes the typedef

+### How to expose the native pointers?
 
-By default all native pointers and typedefs are hidden, but you can use the
-`symbol-address` subkey for functions/globals and make them public by matching with its name. The pointers are then accesible via `nativeLibrary.addresses` and the native typedef are prefixed with `Native_`.
+By default the native pointers are private, but you can use the
+`symbol-address` subkey for functions/globals and make them public by matching with its name. The pointers are then accesible via `nativeLibrary.addresses`.
 
 Example -
 ```yaml
 functions:
   symbol-address:
     include:
-      - 'myFunc'
-      - '.*' # Do this to expose all pointers.
+      - 'myFunc' # Match function name.
+      - '.*' # Do this to expose all function pointers.
+    exclude: # If you only use exclude, then everything not excluded is generated.
+      - 'dispose'
+```
+
+### How to get typedefs to Native and Dart type of a function?
+
+By default these types are inline. But you can use the `expose-typedef` subkey
+for functions to generate them. This will expose the Native and Dart type.
+E.g - for a function named `hello`, the generated typedefs are named
+as `NativeHello` and `DartHello`.
+
+Example -
+```yaml
+functions:
+  expose-typedefs:
+    include:
+      - 'myFunc' # Match function name.
+      - '.*' # Do this to expose types for all function.
+    exclude: # If you only use exclude, then everything not excluded is generated.
+      - 'dispose'
 ```

 ### Why are some typedefs not generated?
 
 The following typedefs are not generated -

-- They refer to a struct/union having the same name as itself.
-- They refer to a boolean, enum, inline array, Handle or any unsupported type.

+### What are these logs generated by ffigen and how to fix them?
+
+Ffigen can sometimes generate a lot of logs, especially when it's parsing a lot of code.
+  - `SEVERE` logs are something you *definitely need to address*. They can be
+    caused due to syntax errors, or more generally missing header files
+    (which need to be specified using `compiler-opts` in config)
+  - `WARNING` logs are something *you can ignore*, but should probably look into.
+    These are mostly indications of declarations ffigen couldn't generate due
+    to limitations of dart:ffi, private declarations (which can be resolved
+    by renaming them via ffigen config) or other minor issues in the config
+    file itself.
+  - Everything else can be safely ignored. It's purpose is to simply
+    let you know what ffigen is doing.
+  - The verbosity of the logs can be changed by adding a flag with
+    the log level. E.g - `dart run ffigen --verbose <level>`.
+    Level options are - `[all, fine, info (default), warning, severe]`.
+    The `all` and `fine` will print a ton of logs are meant for debugging
+    purposes only.

Subject: [PATCH 102/276] [ffigen] BindingsIndex refactor (#283)

Unify and simplify how Types are cached and cycles are broken in the type graph.

- All types that need to be cached (those that have a declaration cursor) are cached in `BindingsIndex._declaredTypes`
- All calls to convert a `CXType` to an ffigen `Type` now go through `getCodeGenType`
- All calls to the related sub-parsers (`parseCompoundDeclaration`, `parseEnumDeclaration`, `parseTypedefDeclaration`) also go through `getCodeGenType`
- Those sub-parsers (mostly) don't know about `BindingsIndex`, and don't know about caching or cycle breaking. That's all handled in one place in `getCodeGenType`
- Cycles are broken by dividing type conversion into 2 stages (the only conversion this matters for is compound types):
    - First the `Type` is created, with as many fields filled in as possible, without a recursive call to `getCodeGenType` (everything except the list of members)
    - Next, `getCodeGenType` inserts the type into the cache
    - Finally, the members are filled in. Recursive calls to `getCodeGenType` are allowed here, as they will hit the cache, breaking any cycles.

-Run `dart test/setup.dart` to build the libraries.
 
-Run tests from the root of the package with `dart run test`.

+
+# ffigen testing
+
+## Running Tests
+
+1.  Some tests require that dynamic libraries be built before running the tests.
+    You can do so with:
+
+    ```shell
+    dart run test/setup.dart
+    ```
+
+2.  Run the tests with:
+
+    ```shell
+    dart test
+    ```
+
+## Development
+
+Some tests verify that the generated Dart FFI bindings match a golden file.
+
+For example, the test
+[`test/native_test/native_test.dart`](https://github.com/dart-lang/ffigen/blob/master/test/native_test/native_test.dart)
+works by:
+
+1.  Loading the dynamic library for
+    [`test/native_test/native_test.c`](https://github.com/dart-lang/ffigen/blob/master/test/native_test/native_test.c)
+    (which was generated by `dart run test/setup.dart`).
+
+2.  Generating binding files for that dynamic library in the
+    `test/debug_generated` directory.
+
+3.  Comparing the golden file (i.e.
+    [`test/native_test/native_test_bindings.dart`](https://github.com/dart-lang/ffigen/blob/master/test/native_test/native_test_bindings.dart))
+    to the generated file and generating a test failure if they do not match.
+
+4.  Using the *golden* bindings to excercise the dynamic library.
+
+If you modify any source for a dynamic library (e.g. any `.c`, `.h` or `.m`
+files), then you should run:
+
+```shell
+   dart run test/setup.dart  # Rebuild the dynamic libraries.
+   dart run test/regen.dart  # Rebuild the golden FFI bindings.
+```
+
+If you modify any code that changes how FFI bindings are generated, then you
+should run:
+
+  ```shell
+  dart run test/regen.dart  # Rebuild the golden FFI bindings.
+  ```
+
+A conservative way to run tests is with:
+
+  ```shell
+  dart run test/setup.dart && dart run test/regen.dart && dart test
+  ```
+
+> Note: you should verify that the changes to the golden bindings are
+> reasonable with `git diff`.

 Ffigen treats `char*` just as any other pointer,(`Pointer<Int8>`).
 To convert these to/from `String`, you can use [package:ffi](https://pub.dev/packages/ffi). Use `ptr.cast<Utf8>().toDartString()` to convert `char*` to dart `string` and `"str".toNativeUtf8()` to convert `string` to `char*`.
-### How does ffigen handle C99 bool data type?
-
-Although `dart:ffi` doesn't have a NativeType for `bool`, they can be implemented as `Uint8`.
-Ffigen generates dart `bool` for function parameters and return type by default.
-To disable this, and use `int` instead, set `dart-bool: false` in configurations.
 
 ### How are unnamed enums handled?

+# Objective C example
+
+This example shows how to use ffigen to generate bindings for an Objective C
+library. It uses the AVFAudio framework to play audio files.
+
+```
+dart play_audio.dart test.mp3
+```
+
+## Config notes
+
+The ffigen config for an Objective C library looks very similar to a C library.
+The most important difference is that you must set `language: objc`. If you want
+to filter which interfaces are included you can use the `objc-interfaces:`
+option. This works similarly to the other filtering options.
+
+It is recommended that you filter out just about everything you're not
+interested in binding (see the ffigen config in [pubspec.yaml](./pubspec.yaml)).
+Virtually all Objective C libraries depend on Apple's internal libraries, which
+are huge. Filtering can reduce the generated bindings from millions of lines to
+tens of thousands.
+
+In this example, we're only interested in `AVAudioPlayer`, so we've filtered out
+everything else. But ffigen will automatically pull in anything referenced by
+any of the fields or methods of `AVAudioPlayer`, so we're still able to use
+`NSURL` etc to load our audio file.
+
+## Generating bindings
+
+At the root of this example (`example/objective_c`), run:
+
+```
+dart run ffigen
+```
+
+This will generate [avf_audio_bindings.dart](./avf_audio_bindings.dart).

-# Objective C example
-
-This example shows how to use ffigen to generate bindings for an Objective C
-library. It uses the AVFAudio framework to play audio files.
-
-```
-dart play_audio.dart test.mp3
-```
-
-## Config notes
-
-The ffigen config for an Objective C library looks very similar to a C library.
-The most important difference is that you must set `language: objc`. If you want
-to filter which interfaces are included you can use the `objc-interfaces:`
-option. This works similarly to the other filtering options.
-
-It is recommended that you filter out just about everything you're not
-interested in binding (see the ffigen config in [pubspec.yaml](./pubspec.yaml)).
-Virtually all Objective C libraries depend on Apple's internal libraries, which
-are huge. Filtering can reduce the generated bindings from millions of lines to
-tens of thousands.
-
-In this example, we're only interested in `AVAudioPlayer`, so we've filtered out
-everything else. But ffigen will automatically pull in anything referenced by
-any of the fields or methods of `AVAudioPlayer`, so we're still able to use
-`NSURL` etc to load our audio file.
-
-## Generating bindings
-
-At the root of this example (`example/objective_c`), run:
-
-```
-dart run ffigen
-```
-

+# Swift example
+
+This example shows how to use ffigen to interact with Swift libraries.
+
+Swift APIs can be made compatible with Objective-C, using the `@objc`
+annotation. Then you can use the `swiftc` tool to build a dylib for the library
+using `-emit-library`, and generate an Objective-C wrapper header using
+`-emit-objc-header-path filename.h`:
+
+```shell
+swiftc -c swift_api.swift               \
+    -module-name swift_module           \
+    -emit-objc-header-path swift_api.h  \
+    -emit-library -o libswiftapi.dylib
+```
+
+This should generate libswiftapi.dylib and swift_api.h.
+For more information about Objective-C / Swift interoperability, see the
+[Apple documentation](https://developer.apple.com/documentation/swift/importing-swift-into-objective-c).
+
+Once you have an Objective-C wrapper header, ffigen can parse it like
+any other header:
+
+```shell
+dart run ffigen
+```
+
+This will generate [swift_api_bindings.dart](./swift_api_bindings.dart),
+using the config in the ffigen section of the pubspec.yaml.
+
+Finally, you can run the example using this command:
+
+```shell
+dart run example.dart
+```
+
+## Config notes
+
+Ffigen only sees the Objective-C wrapper header, swift_api.h. So you
+need to set the language to objc, and set the entry-point to the header:
+
+```yaml
+language: objc
+headers:
+  entry-points:
+    - 'swift_api.h'
+```
+
+Swift classes become Objective-C interfaces, so include them like this:
+
+```yaml
+objc-interfaces:
+  include:
+    - 'SwiftClass'
+```
+
+There is one extra option you need to set when wrapping a Swift library.
+When `swiftc` compiles the library, it gives the Objective-C interface
+a module prefix. Internally, our `SwiftClass` is actually registered
+as `swift_module.SwiftClass`. So you need to tell ffigen about this prefix,
+so it loads the correct class from the dylib:
+
+```yaml
+objc-interfaces:
+  include:
+    - 'SwiftClass'
+  module:
+    'SwiftClass': 'swift_module'
+```
+
+The module prefix is whatever you passed to `swiftc` in the
+`-module-name` flag.

+### How are macros handled?
+
+`ffigen` uses `clang`'s own compiler frontend to parse and traverse the `C` header files. `ffigen` expands the macros using `clang`'s macro expansion and then traverses the expanded code. To do this, `ffigen` generates temporary files in a system tmp directory.
+
+A custom temporary directory can be specified by setting the `TEST_TMPDIR` environment variable.

 ### What are these logs generated by ffigen and how to fix them?
 
 Ffigen can sometimes generate a lot of logs, especially when it's parsing a lot of code.

+
+### How can type definitions be shared?
+
+Ffigen can share type definitions using symbol files.
+- A package can generate a symbol file using the `output -> symbol-file` config.
+- And another package can then import this, using `import -> symbol-files` config.
+- Doing so will reuse all the types such as Struct/Unions, and will automatically
+ exclude generating other types (E.g functions, enums, macros).
+
+Checkout `examples/shared_bindings` for details.
+
+For manually reusing definitions from another package, the `library-imports`
+and `type-map` config can be used.

+> Note: ffigen only supports parsing `C` headers, not `C++` headers.
+
+This bindings generator can be used to call C code -- or code in another
+language that compiles to C modules that follow the C calling convention --
+such as Go or Rust. For more details, see:
+https://dart.dev/guides/libraries/c-interop
+
+ffigen also has experimental support for calling ObjC and Swift code;
+for details see:
+https://dart.dev/guides/libraries/objective-c-interop

+# 8.0.0-dev.0
+
+- Adds `final` class modifier to generated sub types `Struct`, `Union` and
+  `Opaque`. A class modifier is required in Dart 3.0 because the classes
+  `dart:ffi` as marked `base`.
+  When migrating a package that uses FFIgen, _and_ exposes the generated code in
+  the public API of the package, to Dart 3.0, that package does not
+  need a major version bump. Sub typing `Struct`, `Union` and
+  `Opaque` sub types is already disallowed by `dart:ffi` pre 3.0, so adding the
+  `final` keyword is not a breaking change.
+- Bumps SDK lowerbound to 3.0.
+
 # 7.2.10
 
 - Generate parameter names in function pointer fields and typedefs.

 Some tests verify that the generated Dart FFI bindings match a golden file.
 
 For example, the test
-[`test/native_test/native_test.dart`](https://github.com/dart-lang/ffigen/blob/master/test/native_test/native_test.dart)
+[`test/native_test/native_test.dart`](https://github.com/dart-lang/ffigen/blob/main/test/native_test/native_test.dart)
 works by:
 
 1.  Loading the dynamic library for
-    [`test/native_test/native_test.c`](https://github.com/dart-lang/ffigen/blob/master/test/native_test/native_test.c)
+    [`test/native_test/native_test.c`](https://github.com/dart-lang/ffigen/blob/main/test/native_test/native_test.c)
     (which was generated by `dart run test/setup.dart`).
 
 2.  Generating binding files for that dynamic library in the
     `test/debug_generated` directory.
 
 3.  Comparing the golden file (i.e.
-    [`test/native_test/_expected_native_test_bindings.dart`](https://github.com/dart-lang/ffigen/blob/master/test/native_test/_expected_native_test_bindings.dart))
+    [`test/native_test/_expected_native_test_bindings.dart`](https://github.com/dart-lang/ffigen/blob/main/test/native_test/_expected_native_test_bindings.dart))
     to the generated file and generating a test failure if they do not match.
 
 4.  Using the *golden* bindings to excercise the dynamic library.
