NAME
strcasecmp, strncasecmp - compare two strings ignoring case
SYNOPSIS
#include <strings.h>
int strcasecmp(const char *s1, const char *s2);
int strncasecmp(const char *s1, const char *s2, size_t n);
DESCRIPTION
The
strcasecmp()
function compares the two strings s1 and
s2, ignoring the case of the characters.

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
strncasecmp()
function is similar, except it only compares
the first n characters of s1.
RETURN VALUE
The
strcasecmp()
and
strncasecmp()
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.
