NAME
       bcmp - compare byte sequences

SYNOPSIS
       #include <strings.h>

       int bcmp(const void *s1, const void *s2, size_t n);

DESCRIPTION
       The  bcmp() function compares the two byte sequences s1 and s2 of length n each.  If they are equal, and in particular if n is zero, bcmp()
       returns 0.  Otherwise, it returns a nonzero result.

RETURN VALUE
       The bcmp() function returns 0 if the byte sequences are equal, otherwise a nonzero result is returned.
