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.

ATTRIBUTES
   Multithreading (see pthreads(7))
       The memcmp() function is	thread-safe.
