DESCRIPTION         top

       The wcslen() function is the wide-character equivalent of the
       strlen(3) function.  It determines the length of the wide-
       character string pointed to by s, excluding the terminating null
       wide character (L'\0').

RETURN VALUE         top

       The wcslen() function returns the number of wide characters in s.
