[Pythonmac-SIG] Calling OS X libraries from python

[Brendan Simon]

I have found a function in OS X library IOUSBlib called
GetLocationId(self, location) -- specified in IOUSBLib.h

How can I call this function from python ??

Is there a python wrapper for this OS X library ??

If not, what is the best/easiest way to get a python interface to this
library that will interoperate with PyUSB ??

Anyone know if there is a command line utility that I could run to find
this ??

Thanks for any help or suggestions.
Brendan.
