wcscasecmp

WCSCASECMP(3)						     Linux Programmer's Manual						     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:
	       _XOPEN_SOURCE >= 700 || _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.
