<p>
        A move accept handler must meet the requirements for a <a class="link" href="Handler.html" title="Handlers">handler</a>.
        A value <code class="computeroutput">h</code> of a move accept handler class should work correctly
        in the expression <code class="computeroutput">h(ec, s)</code>, where <code class="computeroutput">ec</code> is an lvalue
        of type <code class="computeroutput">const error_code</code> and <code class="computeroutput">s</code> is an lvalue of
        the nested type <code class="computeroutput">Protocol::socket</code> for the type <code class="computeroutput">Protocol</code>
        of the socket class template.

<p>
        A free function as a move accept handler:
      </p>
<pre class="programlisting">void accept_handler(
    const boost::system::error_code&amp; ec, boost::asio::ip::tcp::socket s)
{
  ...
}
</pre>
<p>
        A move accept handler function object:
      </p>
<pre class="programlisting">struct accept_handler
{
  ...
  void operator()(
      const boost::system::error_code&amp; ec, boost::asio::ip::tcp::socket s)
  {
    ...
  }
  ...
};
</pre>
<p>
        A lambda as a move accept handler:
      </p>
<pre class="programlisting">acceptor.async_accept(...,
    [](const boost::system::error_code&amp; ec, boost::asio::ip::tcp::socket s)
    {

    });
</pre>
<p>
        A non-static class member function adapted to a move accept handler using
        <code class="computeroutput">std::bind()</code>:
      </p>
<pre class="programlisting">void my_class::accept_handler(
    const boost::system::error_code&amp; ec, boost::asio::ip::tcp::socket socket)
{
  ...

boost::asio::async_accept(...,
    std::bind(&amp;my_class::accept_handler,
      this, std::placeholders::_1,
      std::placeholders::_2));
