NAME
wcsncasecmp - compare two fixed-size wide-character strings, ignoring
case
SYNOPSIS
#define _GNU_SOURCE
#include <wchar.h>
int wcsncasecmp(const wchar_t *s1, const wchar_t *s2, size_t n);
DESCRIPTION
The 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 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
POSIX.1-2008. This function is not specified in POSIX.1-2001, and is
not widely available on other systems.
NOTES
The behavior of wcsncasecmp() depends on the LC_CTYPE category of the
current locale.
