passing callback function to c-extension

[Diez B. Roggisch]

Hi,

I'm currently writing my first c-extension module. First of all: distutils
and the tutorial for embedding/extending rock! Great work, guys.

However, I didn't find a hint how to pass a python callback function.
Googling didn't turn out much useful stuff, so I'd be glad if someone could
post a hint on how to do this.

Regards,

Diez
