NAME
     memcmp -- compare byte string

SYNOPSIS
     #include <sys/systm.h>

     int
     memcmp(const void *b1, const void *b2, size_t len);

DESCRIPTION
     The memcmp() function compares byte string b1 against byte string b2.  Both strings are
     assumed to be len bytes long.

RETURN VALUES
     The memcmp() function returns zero if the two strings are identical, otherwise returns the
     difference between the first two differing bytes (treated as unsigned char values, so that
     '\200' is greater than '\0', for example).  Zero-length strings are always identical.

STANDARDS
     The memcmp() function conforms to ANSI X3.159-1989 (``ANSI C89'').
