<h2 id="_description">DESCRIPTION</h2>
<div class="sectionbody">
<div class="paragraph">
<p>The <code>nng_sleep_aio()</code> function provides an asynchronous delay mechanism,
causing the callback for <em>aio</em> to be executed after <em>msec</em> milliseconds.
If the sleep finishes completely, the result will always be zero.</p>
</div>

If a timeout is set on <em>aio</em> using
<a href="nng_aio_set_timeout.3.html"><code>nng_aio_set_timeout()</code></a>, and it is shorter
than <em>msec</em>,
then the sleep will wake up early, with a result code of <code>NNG_ETIMEDOUT</code>.
