If you link to pythoncomxx.dll, you can use any of the functions in
pythoncom.h specifically for this purpose.

> ..etc..etc
> // Create a PyObject from the conn Interface to pass to Python
> PyObject * p = Py_BuildValue("O&", converter, *conn);
> // Set the newly created object as a parameter to python
> PyTuple_SetItem(pArgs, 1, p);
> // Call Python
> PyObject_CallObject(func, pArgs);

> My Python program would be something like:
> def func(conn):
> 	# Test if conn object is connected
> 	if conn.IsConnected:
> 		# do something with it

> Any comments greatly appreciated.
