If the above is *really* what you want to access from python, you 
shouldn't bother & write it new in python itself. You could either use

bufLen = len(open(filename).read())

or make a os.stat-call.

If it serves only as a rather ugly illustrative example, then you should 
investigate the ctypes-module of python, which is made for accessing 
arbitrary dlls from python.
