NAME
       strcmp, strncmp - compare two strings

SYNOPSIS
       #include <string.h>

       int strcmp(const char *s1, const char *s2);

       int strncmp(const char *s1, const char *s2, size_t n);

DESCRIPTION
       The  strcmp() function compares the two strings s1 and s2.  It returns an integer less than, equal to, or greater than zero if s1 is found,
       respectively, to be less than, to match, or be greater than s2.

       The strncmp() function is similar, except it only compares the first (at most) n characters of s1 and s2.

RETURN VALUE
       The strcmp() and strncmp() functions return an integer less than, equal to, or greater than zero if s1 (or the first n  bytes  thereof)	is
       found, respectively, to be less than, to match, or be greater than s2.
