NAME
       wcsnlen - determine the length of a fixed-size wide-character string

SYNOPSIS
       #define _GNU_SOURCE
       #include 

       size_t wcsnlen(const wchar_t *s, size_t maxlen);

DESCRIPTION
       The   wcsnlen()	function  is  the  wide-character  equivalent  of  the
       strnlen(3) function.  It returns the number of wide-characters  in  the
       string  pointed to by s, not including the terminating L'\0' character,
       but at most maxlen.  In doing this, wcsnlen() looks only at  the  first
       maxlen wide-characters at s and never beyond s+maxlen.

RETURN VALUE
       The  wcsnlen() function returns wcslen(s), if that is less than maxlen,
       or maxlen if there is no L'\0' character among the  first  maxlen  wide
       characters pointed to by s.

CONFORMING TO
       This function is a GNU extension.
