Yes, you're right, and the 32-bit Windows platform is still important. However, it only works on 32-bit. On typical 64-bit Posix environments, if you don't declare argtypes/restype, you usually end up very quickly with confusion between "int" and "long". And I think that even on 64-bit Windows, passing 0 as a NULL pointer is buggy, because it will pass a 32-bit 0. (It may be that it doesn't actually make a difference and works anyway, but I'm not sure.) Similarly, a function that returns a pointer (e.g. a handle on Windows) will not work without an explicit restype on any 64-bit platform I know of.
Indeed, argument width is quite important :-) Also, on 64-bit Windows, long is 32-bit while size_t and pointers are 64-bit. Regards Antoine.
