NAME
wcsncasecmp - compare two fixed-size wide-character strings, ignoring case
SYNOPSIS
#include <wchar.h>
I int wcsncasecmp(const wchar_t * s1 , const wchar_t * s2 , size_t n );
DESCRIPTION
The
R wcsncasecmp ()
function is the wide-character equivalent of the
strncasecmp(3)
function.
It compares the wide-character string pointed to
by
s1 and the wide-character string
pointed to by
s2, but at most
n wide characters from each string, ignoring case differences
(towupper(3),
towlower(3)).
RETURN VALUE
The
R wcsncasecmp ()
function returns zero
if the wide-character strings at
s1 and s2,
truncated to at most length n, are equal except
for case distinctions.
It returns a positive integer if truncated s1 is
greater than truncated s2, ignoring case.
It returns a negative integer
if truncated s1 is smaller than truncated s2, ignoring case.
CONFORMING TO
This function is a GNU extension.
NOTES
The behavior of
R wcsncasecmp ()
depends on the
LC_CTYPE
category of the
current locale.
