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 n characters of s1.

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
       SVID 3, POSIX, BSD 4.3, ISO 9899
