<p>
This function is used to asynchronously accept a new connection into
a socket, and additionally obtain the endpoint of the remote peer. The
function call always returns immediately.

The socket into which the new connection will be accepted. Ownership
of the peer object is retained by the caller, which must guarantee
that it is valid until the handler is called.
</p></dd>

An endpoint object into which the endpoint of the remote peer will
be written. Ownership of the peer_endpoint object is retained by
the caller, which must guarantee that it is valid until the handler
is called.

<dt><span class="term">handler</span></dt>
<dd>
<p>
The handler to be called when the accept operation completes. Copies
will be made of the handler as required. The function signature
of the handler must be:
</p>
<pre class="programlisting"><span class="keyword">void</span> <span class="identifier">handler</span><span class="special">(</span>
<span class="keyword">const</span> <span class="identifier">asio</span><span class="special">::</span><span class="identifier">error_code</span><span class="special">&</span> <span class="identifier">error</span> <span class="comment">// Result of operation.
</span><span class="special">);</span>
</pre>
<p>
Regardless of whether the asynchronous operation completes immediately
or not, the handler will not be invoked from within this function.
Invocation of the handler will be performed in a manner equivalent
to using <code class="computeroutput"><span class="identifier">asio</span><span class="special">::</span><span class="identifier">io_service</span><span class="special">::</span><span class="identifier">post</span><span class="special">()</span></code>.
