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.
