OK .. ctypes looks great .. and I plan to use it for futur purposes

The fact is that the python interpreter I use is not a standard one
It is a python interpreter delivered within a software named Blender.
I don't know whether it is possible or not to add ctypes to it ..(I 
don't even have a python shell to perform the setup)

I'm sure it is possible to use dll-built with it ..
So please .. can you tell me where I can find Py_BuildValue and 
Py_InitModule4 to link with ?
