</pre>
<p>
This function is used to asynchronously receive data from the raw socket.
The function call always returns immediately.

<div class="variablelist">
<p class="title"><b></b></p>

<dd><p>
One or more buffers into which the data will be received. Although
the buffers object may be copied as necessary, ownership of the
underlying memory blocks is retained by the caller, which must
guarantee that they remain valid until the handler is called.
</p></dd>

<dd><p>
Flags specifying how the receive call is to be made.
</p></dd>
<dt><span class="term">handler</span></dt>
<dd>
<p>
The handler to be called when the receive operation completes.
Copies will be made of the handler as required. The function signature
of the handler must be:
</p>
<pre class="programlisting">void handler(
const boost::system::error_code& error, // Result of operation.
std::size_t bytes_transferred // Number of bytes received.
);
</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">boost::asio::io_context::post()</code>.

</h6>
<p>
The async_receive operation can only be used with a connected socket.
Use the async_receive_from function to receive data on an unconnected
raw socket.
