Nikolas,

You might want to look at SWIG. 

I just finished wrapping a couple of libraries, including SDL
(www.libsdl.org). SDL is a C library and the SDL event structure (a union
actually) might hold a keyboard event which has a nested keysym structure
and so on. 

The structures were wrapped correctly for me although I added some custom
access functions for nested structure members, mostly for performance
reasons. Otherwise every time I try to access the nested structure a copy
of it is allocated and returned to me.

    Thanks, Joel
