This function is used to asynchronously perform an SSL handshake on the
stream. This function call always returns immediately.

<div class="variablelist">
<p class="title"><b></b></p>
<dl>
<dt><span class="term">type</span></dt>
<dd><p>
The type of handshaking to be performed, i.e. as a client or as
a server.
</p></dd>
<dt><span class="term">buffers</span></dt>
<dd><p>
The buffered data to be reused for the handshake. Although the
buffers object may be copied as necessary, ownership of the underlying
buffers is retained by the caller, which must guarantee that they
remain valid until the handler is called.
</p></dd>
<dt><span class="term">handler</span></dt>
<dd>
<p>
The handler to be called when the handshake operation completes.
Copies will be made of the handler as required. The equivalent
function signature of the handler must be:
</p>
<pre class="programlisting">void handler(
const asio::error_code& error, // Result of operation.
std::size_t bytes_transferred // Amount of buffers used in handshake.
);
