<p>The <code>'listening'</code> event is emitted once the <code>dgram.Socket</code> is addressable and
can receive data. This happens either explicitly with <code>socket.bind()</code> or
implicitly the first time data is sent using <code>socket.send()</code>.
Until the <code>dgram.Socket</code> is listening, the underlying system resources do not
exist and calls such as <code>socket.address()</code> and <code>socket.setTTL()</code> will fail.</p>
