- [section:BufferedHandshakeHandler Buffered handshake handler requirements]
- A buffered handshake handler must meet the requirements for a [link
- boost_asio.reference.Handler handler]. A value `h` of a buffered handshake handler
- class should work correctly in the expression `h(ec, s)`, where `ec` is an
- lvalue of type `const error_code` and `s` is an lvalue of type `const size_t`.
- [heading Examples]
- A free function as a buffered handshake handler:
- void handshake_handler(
- const boost::system::error_code& ec,
- std::size_t bytes_transferred)
- {
- ...
- }
- A buffered handshake handler function object:
- struct handshake_handler
- {
- ...
- void operator()(
- const boost::system::error_code& ec,
- std::size_t bytes_transferred)
- {
- ...
- }
- ...
- };
- A non-static class member function adapted to a buffered handshake handler
- using `boost::bind()`:
- void my_class::handshake_handler(
- const boost::system::error_code& ec,
- std::size_t bytes_transferred)
- {
- ...
- }
- ...
- socket.async_handshake(...,
- boost::bind(&my_class::handshake_handler,
- this, boost::asio::placeholders::error,
- boost::asio::placeholders::bytes_transferred));
