What is static_case operator in C++?
<p>I've heard of <a href="http://msdn.microsoft.com/en-us/library/c36yw7x9(VS.80).aspx" rel="nofollow"><strong>static_cast operator</strong></a></p>

<p>Recently I've come across <strong>static_case</strong>, for instance:</p>

<pre><code>*ppv = static_case&lt;IUnknown&gt;
</code></pre>

<p>What does this mean?</p>
