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.
