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.
