boost-asio

I am making a program for school in which two programs communicate with each other. So far I have not been able to connect the two programs. Whenever I try to connect to localhost:8888 or 127.0.0.1:8888, the error "Host not found (authoritative)" occurs. So far my code is this: Connection.cpp Connection::Connection(std::string Arg) { try { tcp::resolver resolver(io_service); cout<<Arg<<endl; tcp::resolver::query query(Arg, "daytime"); tcp::resolver::iterator endpoint_iterator = resolver.resolve(query); tcp::resolver::iterator end; tcp::socket socket(io_service); socket_p = &socket; boost:

Is it possible to detach a native socket from Boost.ASIO's socket class? If so, how can it be done? I can't seem to find anything obvious in the documentation. As a quick overview of what I'm trying to accomplish: I have a class that makes a connection and does some negotiation using Boost.ASIO, then passes back a native Windows SOCKET on success or 0 on failure. Unless I'm mistaken, the native socket will be closed and deallocated when my boost::asio::basic_socket is destructed. Answering my own question. Windows has a WSADuplicateSocket function, which can be used to duplicate the native

As could be read at: https://svn.boost.org/trac/boost/ticket/3504 a deadline_timer that timeouts periodically and which is implemented using deadline_timer::expires_at() (like the example in Boost Timer Tutorial, 3th example ) will probably fail if the system time is modified (for example, using the date command, if your operating system is Linux). Is there a simple and appropiate way of performing this operation now, using Boost? I do not want to use deadline_timer::expires_from_now() because I could verify that it is less accurate than "manually" updating the expiry time. As a temporal

I am going to use boost::asio lib for my project. But it's not quite obvious which function is corresponding to select() from native socket C lib. Is that available in asio? Or does boost provide an alternative to find out if a socket is ready? The high-level design of Boost.Asio is based on the Proactor desing pattern . Thus, you don't need to poll on select . Instead, submit your completion handler for an asynchronous operation, and when the operation gets completed - the completion handler gets called. The documentation has a specific section for mapping the BSD socket API calls into their

I'm modify the Boost Asio echo example to use async_read_until to read the input word by word. Even though I am using async_read_until , all the data sent seems to be read from the socket. Could someone please advise: #include <cstdlib> #include <iostream> #include <boost/bind.hpp> #include <boost/asio.hpp> using boost::asio::ip::tcp; class session { public: session(boost::asio::io_service& io_service) : socket_(io_service) { } tcp::socket& socket() { return socket_; } void start() { std::cout<<"starting"<<std::endl; boost::asio::async_read_until(socket_, buffer, ' ', boost::bind(&session:

I'm working with Intel SGX which has predefined structures. I need to send these structures over a network connection which is operated by using boost::asio . The structure that needs to be send has the following format: typedef struct _ra_samp_request_header_t{ uint8_t type; /* set to one of ra_msg_type_t*/ uint32_t size; /*size of request body*/ uint8_t align[3]; uint8_t body[]; } ra_samp_request_header_t; For the sending and receiving, the methods async_write and async_async_read_some are used boost::asio::async_write(socket_, boost::asio::buffer(data_, max_length), boost::bind(&Session:
