A handshake handler must meet the requirements for a handler.
A value h
of a handshake
handler class should work correctly in the expression h(ec)
,
where ec
is an lvalue of
type const error_code
.
A free function as a handshake handler:
void handshake_handler( const asio::error_code& ec) { ... }
A handshake handler function object:
struct handshake_handler { ... void operator()( const asio::error_code& ec) { ... } ... };
A non-static class member function adapted to a handshake handler using
bind()
:
void my_class::handshake_handler( const asio::error_code& ec) { ... } ... ssl_stream.async_handshake(..., boost::bind(&my_class::handshake_handler, this, asio::placeholders::error));
