c++ pointer to a reference
<p>Is it legal to have a pointer of a reference in C++? </p>

<p>For example:</p>

<pre><code>int &amp;ref = array[idx];
func(&amp;ref);
</code></pre>

<p>One reason I can think of why you might want to do this if func() already exists in a library which you can't change.</p>
