            This function is used to receive data on the stream socket. The function
            call will block until one or more bytes of data has been received successfully,
            or until an error occurs.

<p>
            The receive operation may not receive all of the requested number of
            bytes. Consider using the <a class="link" href="../../read.html" title="read"><code class="computeroutput">read</code></a>
            function if you need to ensure that the requested amount of data is read
            before the blocking operation completes.

            To receive into a single data buffer use the <a class="link" href="../../buffer.html" title="buffer"><code class="computeroutput">buffer</code></a>
            function as follows:
          </p>
<pre class="programlisting">socket.receive(boost::asio::buffer(data, size), 0);
</pre>
<p>
            See the <a class="link" href="../../buffer.html" title="buffer"><code class="computeroutput">buffer</code></a>
            documentation for information on receiving into multiple buffers in one
            go, and how to use it with arrays, boost::array or std::vector.
