NAME
       memcmp - compare memory areas

SYNOPSIS
       #include <string.h>

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

DESCRIPTION
       The memcmp() function compares the first n bytes (each interpreted as unsigned char) of the memory areas s1 and s2.

RETURN VALUE
       The memcmp() function returns an integer less than, equal to, or greater than zero if the first n bytes of s1 is found, respectively, to be
       less than, to match, or be greater than the first n bytes of s2.

       For a nonzero return value, the sign is determined by the sign of the difference between the first pair of bytes (interpreted  as  unsigned
       char) that differ in s1 and s2.
