Small demonstration of ctypesgen

This example shows how to quickly generate bindings for a simple C library using ctypesgen and access them in a Python script.

Steps

1. Compile the shared C library

   gcc -fPIC -shared demolib.c -o demolib.so

2. (Re-)Generate the bindings (or you can just try the pre-generated bindings already present in this directory)

   ctypesgen -i demolib.h -l demolib -L . -o pydemolib.py

3. Run the app that uses these generated bindings

   python demoapp.py

   The call should yield the following output:

   a 1
   b 2
   result 3
   

4. You can also try calling the same code from a C executable

   • Compile test code:

     gcc demoapp.c demolib.c demolib.h -o demoapp
     

   • Run ./demoapp

   • Observe the same results as before:

     a 1
     b 2
     result 3
