Registering a python function in C

[fernando]

Could someone post an example on how to register a python function as
a callback in a C function? It expects a pointer to PyObject... how do
I expose that? Basically, the signature of the function is
foo(PyObject* obj), where obj is the callback function... It's not
exactly extending or embedding, I've looked at those examples but they
don't really show how to do this...

Thanks for the help!
