<pre><code> You can simply mark the function as `noexcept`, that's it. If there

<p>Both of the two possibly called constructors of <code>std::unique_ptr</code> are marked <code>noexcept</code>. The one accepting <code>U const&</code> requires <code>U</code> to have a <em>nothrow copy-constructible</em>, and the one accepting <code>U&&</code> requires <code>U</code> to have a <em>nothrow move-constructible</em>.</p>

<pre><code> Hm, do you mean having a default param = &free for the releaser?</code></pre>

<p>I simply meant calling one from the other, easier to document and easier for people to understand - also not too sure if doxygen handles default <em>template-arguments</em> that well (if at all).</p>
