NAME

       wcscasecmp - compare two wide-character strings, ignoring case

SYNOPSIS

       #define _GNU_SOURCE
       #include <wchar.h>

       int wcscasecmp(const wchar_t *s1, const wchar_t *s2);

DESCRIPTION

       The  wcscasecmp()  function  is  the  wide-character  equivalent of the
       strcasecmp(3) function.  It compares the wide-character string  pointed
       to  by s1 and the wide-character string pointed to by s2, ignoring case
       differences (towupper(3), towlower(3)).

RETURN VALUE

       The wcscasecmp() function returns zero if the wide-character strings at
       s1  and  s2  are  equal  except  for  case  distinctions.  It returns a
       positive integer if s1 is greater than s2, ignoring case.  It returns a
       negative integer if s1 is smaller than 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 wcscasecmp() depends on the LC_CTYPE  category  of  the
       current locale.
