bcmp() - compare byte string
#include <strings.h>
int bcmp (const void *b1, const void *b2, size_t len)
The bcmp(3) function compares byte string b1 against byte string b2, returning zero if they are identical, non-zero otherwise. Both strings are assumed to be len bytes long. Zero-length strings are always identical.
The strings may overlap.
