It most definitely is extending or embedding, it just doesn't follow
the examples provided. I can't be too specific because I don't know
what your environment is like. As in, have you already initialized
python and all of that? Do you have access to _any_ PyObject*
variables?

Here is something that _might_ help (not tested):
[code]
PyObject* mod;
PyObject* func;

mod = PyImport_ImportModule("mymodule");
func = PyObject_GetAttrString( mod, "myfunc") ;
foo(func);
[/code]

It might be useful to look at the "Python/C API Reference Manual", not
just the extending and embedding stuff.
