STRCMP(3) Linux Programmer's Manual STRCMP(3)

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 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.
