wcscasecmp(3)

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.

   not widely available on other systems.

   The  behavior  of  wcscasecmp() depends on the LC_CTYPE category of the
   current locale.
