[Pythonmac-SIG] ctypes and OS X CF types?

[Daniel Miller]

Please ignore my previous email. I hope it didn't come across as  
condescending. Really, I was only trying to help. Unfortunately, I  
had not read your question thoroughly enough.

Are you asking about struct definitions and such? For example:

from ctypes import Structure, c_float, c_double

class PMRect(Structure):
     _fields_ = [
         ("top", c_double),
         ("left", c_double),
         ("bottom", c_double),
         ("right", c_double),
     ]

class CGPoint(Structure):
     _fields_ = [("x", c_float), ("y", c_float)]

class CGSize(Structure):
     _fields_ = [("width", c_float), ("height", c_float)]

class CGRect(Structure):
     _fields_ = [("origin", CGPoint), ("size", CGSize)]

Those are the only ones I've used, and luckily they're pretty simple.  
I do not know of a library of definitions for standard CF types. Sorry.
