You can also try SWIG (cvs version) it fully supports C.

thanks, I've tried it and now it generates a mapping for e.g. TCL (which is 16 mb), but when specifying -cffi, it reports some messages (see below) and generates only a 6000 line lisp file for CFFI, with all mappings until GENERIC_MAPPING, but all other missing. Deleting this stops at the next structure. Looks like the CFFI support is missing some features. This is the command line I've used: swig -DGUID_DEFINED -D_TCHAR_DEFINED -D_M_IX86 -D_WIN32 \ -Iwindows -Iwindows/w32api -includeall -cffi interface.i and this the interface.i: %include "windows.i" %module windows %{ #include "windows.h" %} %include "windows.h" I've used the cygwin header files and patched it a bit to fix some errors, you can download the package at http://www.frank-buss.de/tmp/cffi.zip I'll post this to the cffi-devel mailing list, too, perhaps someone can take a look at it and fix the cffi swig module.
