NAME

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

SYNOPSIS

       #define _GNU_SOURCE
       #include <wchar.h>

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

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
       (towupper(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.

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.
