This is covered in the documentation, isn't it? <http://docs.python.org/library/ctypes.html#callback-functions> Important note for callback functions: Make sure you keep references to CFUNCTYPE objects as long as they are used from C code. ctypes doesn't, and if you don't, they may be garbage collected, crashing your program when a callback is made.
