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

1 Oct 2011

      I want to make a callback that also calls back. 
I cannot get the code to compile. 

I read on the boost documentation about apply()., but the example is 
unclear and I am not sure if that is what I am looking for. 

/// 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?
