Hello, i'm using boost 1.34 with the asio c++ library extension for socket communication. At the moment i have following problem. - i open a client class with usage of io service and a connection manager according to the examples TcpClient* client = new TcpClient(ioServiceClient, string(regServer->host), Utilities::intToString(regServer->port), connectionManager, *this); - after connected to a server i send some messages via asio::async_write(socket_, buffer, boost::bind(&TcpConnection::handle_write, shared_from_this(), asio::placeholders::error)); - the connection itself listen to incoming messages via asio::async_read(socket_, asio::buffer(inbound_header_), boost::bind(&TcpConnection::handle_read_header, shared_from_this(), asio::placeholders::error)); So what i have to do is - open connection - send some messages - disconnect The disconnect is done ioServiceClient.post(boost::bind(&ConnectionManager::stop_all, &connectionManager)); So what is my problem: I need to close the connection after sending the last message. At a certain message length the disconnect happens before the message was send completely. That's why i thought putting the disconnect via post to the io service will handle this. But this is not the case. How can i make a clean disconnect when all outstanding messages were send completely?? Thanks for your answers.
