43            This function is used to send a <a href="https://tools.ietf.org/html/rfc6455#section-5.5.1" target="_top">close
44            frame</a>, which begins the websocket closing handshake. The session
45            ends when both ends of the connection have sent and received a close
46            frame. The call blocks until one of the following conditions is true:
47          </p>
48<div class="itemizedlist"><ul class="itemizedlist" style="list-style-type: disc; ">

57            The algorithm, known as a <span class="emphasis"><em>composed operation</em></span>, is
58            implemented in terms of calls to the next layer's <code class="computeroutput"><span class="identifier">write_some</span></code>
59            function. After beginning the closing handshake, the program should not
60            write further message data, pings, or pongs. Instead, the program should
61            continue reading message data until an error occurs. A read returning
