wcscasecmp — compare two wide-character strings,
ignoring case
Synopsis
#define _GNU_SOURCE
#include <wchar.h>
int
wcscasecmp(
const wchar_t *
s1,
const wchar_t *
s2);
DESCRIPTION
The wcscasecmp() function is
the wide-character equivalent of the strcasecmp(3) function. It
compares the wide-character string pointed to by s1 and the wide-character
string pointed to by s2, ignoring case differences
(towupper(3), towlower(3)).
RETURN VALUE
The wcscasecmp() function
returns zero if the wide-character strings at s1 and s2 are equal except for case
distinctions. It returns a positive integer if s1 is greater than s2, ignoring case. It returns a
negative integer if s1 is smaller than s2, ignoring case.
CONFORMING TO
This function is a GNU extension.
NOTES
The behavior of wcscasecmp()
depends on the LC_CTYPE
category of the current locale.
