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

SYNOPSIS
       #define _GNU_SOURCE
       #include <wchar.h>

       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'' 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'' character among the first maxlen wide
       characters pointed to by s.

CONFORMING TO
       This function is a GNU extension.
