     #include <string.h>

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

DESCRIPTION
     The memcmp() function compares byte string s1 against byte string s2.
     Both strings are assumed to be n bytes long.

RETURN VALUES
     The memcmp() function returns zero if the two strings are identical, oth‐
     erwise 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.
