Matt Clarke added the comment: It seems that any argument greater than 8 bytes is automatically converted to a references. Thus, changing to using ctypes.POINTER works. For example:
callback_t = ctypes.CFUNCTYPE(None, ctypes.POINTER(myst_args)) Quite a simple solution in the end. Is it worth documenting this on the ctypes page?
