NAME

       wcsncasecmp - compare two fixed-size wide-character strings, ignoring case

SYNOPSIS

       #include <wchar.h>

       int wcsncasecmp(const wchar_t *s1, const wchar_t *s2, size_t n);

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

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

DESCRIPTION

       The  wcsncasecmp() function is the wide-character equivalent of the strncasecmp(3) function.  It compares the wide-character string pointed
       to by s1 and the wide-character string pointed to by s2, but at most n wide characters from each string, ignoring case differences  (towup-
       per(3), towlower(3)).

RETURN VALUE

       The  wcsncasecmp()  function  returns  zero if the wide-character strings at s1 and s2, truncated to at most length n, are equal except for
       case distinctions.  It returns a positive integer if truncated s1 is greater than truncated s2, ignoring case.  It returns a negative inte-
       ger if truncated s1 is smaller than truncated s2, ignoring case.

VERSIONS

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