Really?  The part about "functions that call those" sounds a bit off.
I thought Python functions that call globals() would work.
Each Python function contains a pointer to its globals namespace
(the fn.func_globals attribute), and calling a Python function
creates a PyFrameObject.  It seems as though it should work.

So, what are you really trying to do?  :)  I have a feeling that
calling vars() directly from C is a mistake; there's probably an
easier way to do what you need.

For example, if you just want to look at module's namespace,
that's easy:

  result = PyModule_GetDict(module);
