NAME
strcasecmp, strncasecmp - compare two strings ignoring
case
SYNOPSIS
#include <string.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. 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 strncasecmp() function is similar, except it only com-
pares 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.
