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 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.

CONFORMING TO
       SVr4, 4.3BSD, C89, C99.
