u need to reserve at
        least <code class="literal">len+1</code> bytes for the string that <code class="literal">dest</code>
        points to. The function copies at most <code class="literal">len</code> bytes to the new
        location (less if the source string has trailing blanks) and adds the
        null-terminator.
