<div class="sectionbody">
<div class="paragraph">
<p>These functions allocates a dialer for byte streams.
Dialers create
<a href="nng_stream.5.html"><code>nng_stream</code></a> objects by initiating outgoing
connections, via the
<a href="nng_stream_dialer_dial.3str.html"><code>nng_stream_dialer_dial()</code></a> function.</p>
</div>
<div class="paragraph">
<p>The first form, <code>nng_stream_dialer_alloc()</code>, connects to the address
specified by <em>addr</em>, which should be a string representing a URL.</p>
</div>
<div class="paragraph">
<p>The second form, <code>nng_stream_dialer_alloc_url()</code>, takes a pre-parsed
or pre-constructed
<a href="nng_url.5.html"><code>nng_url</code></a> object to determine the remote address.</p>
</div>
<div class="paragraph">
<p>These functions may support different URL schemes, such as
<code>ipc://</code>, <code>tcp://</code>, <code>tls+tcp://</code>, or <code>ws://</code>.</p>
</div>
<div class="paragraph">
<p>Both forms store the dialer in the location referenced by <em>dp</em>.</p>
