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.  The locale is not taken into
       account (for a locale-aware comparison, see strcoll(3)).  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 compares only the first (at most) n bytes  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.
