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 str-
     casecmp(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 posi-
     tive 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.

     current locale.
