NAME

       wcscasecmp - compare two wide-character strings, ignoring case

SYNOPSIS

       #include <wchar.h>

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

   Feature Test Macro Requirements for glibc (see feature_test_macros(7)):

       wcscasecmp():
           Since glibc 2.10:
               _POSIX_C_SOURCE >= 200809L
           Before glibc 2.10:
               _GNU_SOURCE

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.

VERSIONS

       The wcscasecmp() function is provided in glibc since version 2.1.

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.
