<p>The <code>nng_stream_close()</code> function closes the
<a href="nng_stream.5.html">byte stream</a> <em>s</em>.</p>
</div>
<div class="paragraph">
<p>If any operations are pending, such as
<a href="nng_stream_send.3str.html"><code>nng_stream_send()</code></a>
or
<a href="nng_stream_recv.3str.html"><code>nng_stream_recv()</code></a>,
they will be terminated with
an <code>NNG_ECLOSED</code> error condition.
Also, any new operations will fail with <code>NNG_ECLOSED</code> after the connection
is closed.</p>

Closing the connection while data is in transmission will likely
lead to loss of that data.
There is no automatic linger or flush to ensure that the socket send buffers
have completely transmitted.

Closing the connection does not free the resources associated with it.
Once it is certain that no more operations are pending on the connection,
it should be freed with
