Re: [Boost-users] Callback that calls a callback using boost::bind

/// Smart Pointer typedef boost::shared_ptr<TcpServerSideConnection> SmartPtr;

/// Callback function pointer type for TcpListener notification that our execution of /// TcpServerSideConnection::OnConnectionAccepted has completed typedef boost::function<void(TcpServerSideConnection::SmartPtr newConnection,                                 const boost::system::error_code & error)> ConnectionAcceptedListenerCallback;

/// Callback function pointer type for TcpServerSideConnection notification of /// a TcpListener::Listen IO completion typedef boost::function<void(ConnectionAcceptedListenerCallback listenerCallback,                                 const boost::system::error_code & error)> ConnectionAcceptedCallback;

TcpListener::SmartPtr me = boost::dynamic_pointer_cast<TcpListener, TcpBaseSocket>(shared_from_this());

TcpServerSideConnection::ConnectionAcceptedListenerCallback listenerCallback =        boost::bind(&TcpListener::OnConnectionAccepted, me, _1, _2);

TcpServerSideConnection::ConnectionAcceptedCallback acceptCompleteCallback =        boost::bind(&TcpServerSideConnection::OnConnectionAccepted, newConnection, listenerCallback, boost::asio::placeholders::error);

acceptor_.async_accept(newConnection->GetSocket(), acceptCompleteCallback);

Gives me a compile error in bind.hpp with 100s of pages.

What am I doing wrong here? Does anyone have an example of a callback that callsback using boost::bind?

In general, I think you should use boost::protect around "listenerCallback", but if you need help with exact expression, please provide a self-contained sample.
