Reread the original. It *does* do a 32 bit copy. Still, one should use bcopy/memcopy/memmove/whatever-we-call-it-this-week. I suspect it can be optimised a bit more (copy 64 bytes per trip around the main loop, e.g.). -- In-Real-Life: Chris Torek, Univ of MD Comp Sci Dept (+1 301 454 7163) Domain: chris@mimsy.umd.edu Path: uunet!mimsy!chris
