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

NAME         top

       strcmp, strncmp - compare two strings

SYNOPSIS         top

       #include <string.h>

       int strcmp(const char *s1, const char *s2);

       int strncmp(const char *s1, const char *s2, size_t n);

DESCRIPTION         top

       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         top

       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.
