has anyone ever used memset with a c arg other than 0? why?

also 8-byte, in case you want to fill a region with identical pointers I guess and "just write a loop" isn't as fast; memset is actually has asm optimizations in most libcs (for small buffers it's SIMD; for large it's cache-bypassing REP STOS)

I often have memset8, memset16, memset32 when I'm building freestanding systems, along with all the other useful memory operations. This is on 32-bit systems; on 64-bit ones I'd add that variant too.pic.twitter.com/gbdXLhpfUM
