NAME
       memcmp - compare bytes in memory

SYNOPSIS
       #include <string.h>

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

DESCRIPTION
       The memcmp() function shall compare the first n bytes (each interpreted as unsigned char) of the object pointed to by s1  to  the  first  n
       bytes of the object pointed to by s2.

       The  sign  of a non-zero return value shall be determined by the sign of the difference between the values of the first pair of bytes (both
       interpreted as type unsigned char) that differ in the objects being compared.

RETURN VALUE
       The memcmp() function shall return an integer greater than, equal to, or less than 0, if the object pointed to by s1 is greater than, equal
       to, or less than the object pointed to by s2, respectively.
