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:
               _XOPEN_SOURCE >= 700 || _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 integer 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.
