SuSE 11.3 - man page for wcsncasecmp (suse section 3)

WCSNCASECMP(3)			    Linux Programmer's Manual			   WCSNCASECMP(3)

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) func-
       tion.  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,  trun-
       cated  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  nega-
       tive 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.
