Perhaps you can use None, I'm not sure. However, I used c_voidp, not c_void_p. c_voidp as far as I am aware means void parameter, not void pointer. c_voidp can be used in ctypes function declarations for the return type when it is void.
c_void_p is void pointer. Mick On 15/03/2009 5:38 AM, Michael Eddington wrote: > Correct me if I'm wrong, but I think you just defined it to return a > "void*" (c_voidp).
