 A memory-mapped file is created by the :class:`~mmap.mmap` constructor, which is
 different on Unix and on Windows.  In either case you must provide a file
 descriptor for a file opened for update. If you wish to map an existing Python

 :func:`os.open` function, which returns a file descriptor directly (the file
 still needs to be closed when done).
