I'm intending to use STAF - software testing automation framework where I
want to test this dll. Test cases for STAF are written in xml and python. So
for this I want to write a wrapper class for this dll in python that has Dll
API's as the member function of the wrapper class.

This class will be in a python module. This module can be then be imported
in the test cases thereby exposing the dll APIs for testing.

Please suggest if there are better solutions around.

Well I did not know this. What is a Python extension module?
