NAME

       wcscasecmp - compare two wide-character strings, ignoring case

LIBRARY

       Standard C library (libc, -lc)

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 since glibc 2.1.

STANDARDS

       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.
