Start an asynchronous SSL handshake.
template< typename HandshakeHandler = DEFAULT> DEDUCED async_handshake( handshake_type type, HandshakeHandler && handler = DEFAULT);
This function is used to asynchronously perform an SSL handshake on the stream. This function call always returns immediately.
The type of handshaking to be performed, i.e. as a client or as a server.
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:
void handler( const boost::system::error_code& error // Result of operation. );
This asynchronous operation supports cancellation for the following
cancellation_type
values:
cancellation_type::terminal
cancellation_type::partial
if they are also supported by the Stream
type's async_read_some
and async_write_some
operations.
