wcsncasecmp(3) -- Linux man page
NAME
wcsncasecmp - compare two fixed-size wide-character strings, ignoring case
SYNOPSIS
#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 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, towlower).
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
This function is a GNU extension.

NOTES
The behaviour of wcsncasecmp depends on the LC_CTYPE category of the
current locale.
