That's okay too. The function could be PyInt_AsUnsignedLong(). It
could convert negative 32-bit ints to unsigned as a backward
compatibility measure (with warning?) that will eventually disappear.
The format code could be 'I' for unsigned int, but I don't know what
to use for unsigned long. Or perhaps still use 'k'/'K' for masK?
