NAME

6       strcmp, strncmp - compare two strings
7

SYNOPSIS

9       #include <string.h>
10
11       int strcmp(const char *s1, const char *s2);
12
13       int strncmp(const char *s1, const char *s2, size_t n);
14

DESCRIPTION

16       The  strcmp()  function compares the two strings s1 and s2.  It returns
17       an integer less than, equal to, or greater than zero if  s1  is  found,
18       respectively, to be less than, to match, or be greater than s2.
19
20       The  strncmp()  function  is similar, except it compares only the first
21       (at most) n bytes of s1 and s2.
22

RETURN VALUE

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