Hi all - quick ctypes question.

I'm experimenting with stencil buffer picking and I need to pass an
array of GLuints to glSelectBuffer. Problem is, while my research has
turned up information about passing simple types by reference, I'm
having trouble nutting out passing an array. I'm sure I'm missing
something simple - If you can help, lemme know what it is so I can get
to the forehead-slapping stage. :)

Here's a simple run-down of the code:

BUFSIZE = 512
selectBufType = GLuint * BUFSIZE
selectBuf = selectBufType()

# This version causes "ctypes.ArgumentError: argument 2:
# exceptions.TypeError: expected LP_c_long instance instead of
_ctypes.ArrayType"
glSelectBuffer(BUFSIZE, selectBuf)

# This version causes "ctypes.ArgumentError: argument 2:
# exceptions.TypeError: expected LP_c_ulong instance instead of
pointer to c_ulong_Array_512
glSelectBuffer(BUFSIZE, byref(selectBuf))


Any ideas?
