I agree with others that ctypes might be your best path. The codeGenerator is magic, if you ask me: http://starship.python.net/crew/theller/ctypes/old/codegen.html But, if the function is simple, why not weave.inline? What I have done is run the function once, hunt down the long-named library, copy it to the local directory, then include it explicitly and call its function. This eliminates some overhead time for the call. I use it to convert packed IEEE data from an ADC data read function, and it's faster than the manufacturer's own function version that returns scaled integers!
