In ANSI C the basic types are not defined in terms of bits, however there is a minimum magnitude required. An unsigned long is supposed to hold at least 4294967295, which is 2^32-1. On most normal platforms, that means an unsigned long must be at least 32 bits. -- Chris Adams <cmadams@hiwaay.net> Systems and Network Administrator - HiWAAY Internet Services I don't speak for anybody but myself - that's enough trouble.
