Let python call a C function pointer passed from the C Python API

[hvictor]

I have C++ a void function pointer stored in a variable call. The
pointed function takes an int and a char* as arguments.

I have a python module containing this function:

def yeah(x):
	x(int(0),"text argument")
	return "pointer called"

As you can see I'm trying to use the argument x of the function like a
method object.
In the C++ side I'm doing following (note that I only paste relevant
parts of code because this system is working fine, C++ is able to call
function yeah and get its return value, but only with a string-
oriented test):
...
PyObject *pValue; // the argument for python

pValue = PyCObject_FromVoidPtr(call,destr); // destr is a void fctn
ptr, required from the api.

PyObject *pFunc = PyObject_GetAttrString(pModule, "yeah");

...
PyTuple_SetItem(pArgs, 0, pValue); // pArgs is a pyobject, the
arguments, I insert pValue in it.

pValue = PyObject_CallObject(pFunc, pArgs);

...

It does not work. can anyone help me please? I just want python to
call this function pointer.

Thank you
