Executing a specific function.

[Michael Saunders]

Martin,

I had seen this API but it requires a "callable". Isn't a callable a PyObject
pointer to a callable function? How do I build the "callable". All I have is a
Python file, "myfile.py" and the name of a function to call "myPthonFunction".

PyObject* PyObject_CallFunction(PyObject *callable, char *format, ...) 
     Return value: New reference. 
     Call a callable Python object callable, with a variable number of C
     arguments. The C arguments are described using a Py_BuildValue() style
     format string. The format may be NULL, indicating that no arguments are
     provided. Returns the result of the call on success, or NULL on failure.
     This is the equivalent of the Python expression "apply(callable, args)"
     or "callable(*args)".
