       The strnlen()  function returns the number of bytes in the string
       pointed to by s, excluding the terminating null byte ('\0'), but at
       most maxlen.  In doing this, strnlen()  looks only at the first maxlen
       characters in the string pointed to by s and never beyond s[maxlen-1].

       The strnlen()  function returns strlen(s), if that is less than maxlen,
       or maxlen if there is no null terminating ('\0') among the first maxlen
       characters pointed to by s.
