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. 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 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.
