Yes, I figured that out by now. Sadly this doesn't work on "file-like"
objects like those that are created by opening bz2 files (using the
bz2 lib). Not that I have any idea on how that should work anyway.

I still can resolve this issue in my wrapper module and let the C part
deal with the raw buffer contents.

All in all I must say that implementing a C extension is a piece of
cake. Had I known that it was this straightforward I wouldn't have
asked my questions in the first place. Making the whole thing more
robust will be a bit more difficult, and I need to find out how to
deal with ressources that are dynamically allocated on the C side.

But that should be easy, and I'll just keep all the Python OO and
Exceptions stuff in the wrapper and call my C stuff from there in a
more or less straightforward C manner.

Thanks to everybody for helping out,

robert
