[Pyobjc-dev] Wrapping GetLocationID from IOUSBLib

[Brendan S. (eTRIX) <Bre...@eT...>]

I'm new to PyObjC (and Object C in general).

I have a python application that accesses a USB device, and I want to
display the LocationID (like System Profiler and ioreg does).

The LocationID seems to be OS X specific and not part of the standard
USB protocol and thus not part of PyUSB.

So assuming OS X does not provide a python interface to IOUSBLib (please
let me know if it does), then I have to find a way to access it from
Python.  It would seem that PyObjC would be an appropriate method --
yes/no ???

The header file IOUSBLib.h contains the function GetLocationID.

    IOReturn (*GetLocationID)(void *self, UInt32 *locationID);

Am I able to wrap this one function (or is it a method ?) easily with
PyObjC ??

If it is easy, could someone provide some skeleton code for me to
work/play with.
If not so easy, could someone outline things that need to done and point
me to some appropriate doucmentation.

Many thanks, Brendan (pyobjc newbie) :)
