I am not sure you need this, but if you ask:
http://pygccxml.svn.sourceforge.net/viewvc/pygccxml/pyplusplus_dev/docs/documentation/ctypes/

The link contains few documents, which describes the idea and
implementation behind "Py++ & ctypes integration".

If you are wrapping pure C code, I suggest you to stay with ctypeslib
only. The overhead is too big.

This is exactly my plan - to port current code generator to deal with
pygccxml and not with xml directly.
