For example async_read_until() can be used on protocols where a certain set of characters are used to indicate the end of a message, and async_read() can be used for either fixed-length

Am I doing it right? you can file a bug against boost asio to transform this error code to boost::asio::error::eof. One server uses the following code to send data: std::shared_ptr s = std::make_shared(message); boost::asio::async_write(socket_, boost::asio::buffer(*s), std::bind(&TcpServer::HandleWrite, shared_from_this(), s, _1, _2)); In another TcpServer, when I use async_read_until to get data, everything message_size = BOOST_ASIO_SOCKET_ERROR(EMSGSIZE), /// The name was too long.

tcp::resolver::iterator endpoint_iterator = resolver.resolve(query); tcp::resolver::iterator end; Now we create and connect the socket. Shut down the client. I had the exact same problem and I am quite sure that this is a bug of boost::asio 1.54.0 Here is the bug report. deadline_.expires_from_now(boost::posix_time::seconds(60)); // Start the asynchronous connect operation.

The solution is effectively to get back to 1.53, although there is a patch available for 1.54 in the bug report page. A client connects to the server, reads from the socket the message, and terminates. Typically when having variable length messages, you define some kind of packet format e.g. deadline_.async_wait(boost::bind(&tcp_client::check_deadline, this)); } private: bool stopped_; tcp::socket socket_; boost::asio::streambuf input_buffer_; deadline_timer deadline_; deadline_timer heartbeat_timer_; std::vector *requests, *responses, *eots; unsigned int last_request=0; unsigned int request_timeout = 30; unsigned int connect_timeout = 10;

Now I am ready to open the connection on a socket.
