NAME
     memcmp — compare byte string

LIBRARY

SYNOPSIS
     #include <string.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, 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.
