  1. POWhy does boost::asio appear to do nothing
    text
    copied!<p>I'm trying to implement the irc protocol in a very basic manner. My first attempt is to use boost::asio and connect to a server and read the motd. AFAIK the motd is sent to every client when they connect. I have made the following test program and it seems to not do anything. It's not a very good piece of code but this is all I have after several frustrating hours.</p> <pre><code>#define _WIN32_WINNT 0x0501 #include &lt;iostream&gt; #include &lt;boost/asio.hpp&gt; #include &lt;boost/bind.hpp&gt; #include &lt;boost/function.hpp&gt; #include &lt;queue&gt; class IrcConnection { public: IrcConnection(const std::string&amp; server, int port, boost::function&lt;void (const std::string&amp;)&gt; onMessage, boost::asio::io_service&amp; io_service): s(server), p(port), onM(onMessage), ios(io_service), socket(io_service) { } void connect() { somethingHappened = false; //DNS stuff boost::asio::ip::tcp::resolver resolver(ios); boost::asio::ip::tcp::resolver::query query(s , "0"); boost::asio::ip::tcp::resolver::iterator iter = resolver.resolve(query); boost::asio::ip::tcp::resolver::iterator end; boost::system::error_code error; while(iter != end) { boost::asio::ip::tcp::endpoint endpoint = iter-&gt;endpoint(); endpoint.port(p); socket.close(); socket.connect(endpoint, error); iter++; } if(error) { std::cout &lt;&lt; "ERROR" &lt;&lt; std::endl; std::cout &lt;&lt; error &lt;&lt; std::endl; } std::cout &lt;&lt; "Connected to: " &lt;&lt; socket.remote_endpoint().address().to_string() &lt;&lt; std::endl; //read from the socket until a space is found boost::asio::async_read_until(socket, currentData, ' ', boost::bind(&amp;IrcConnection::onReceiveFinished, this, boost::asio::placeholders::error)); } void disconnect() { socket.close(); } void send(int priority, const std::string&amp; message) { } bool somethingHappened; private: std::string s; int p; boost::function&lt;void (const std::string&amp;)&gt; onM; boost::asio::io_service&amp; ios; boost::asio::ip::tcp::socket socket; std::priority_queue&lt;std::string&gt; outQueue; boost::asio::streambuf currentData; void onReceiveFinished(const boost::system::error_code&amp; error) { if(error) { disconnect(); std::cout &lt;&lt; "ERRORRRR" &lt;&lt; std::endl; std::cout &lt;&lt; error &lt;&lt; std::endl; } std::cout &lt;&lt; "STUFF IS OCCURING" &lt;&lt; std::endl; somethingHappened = true; std::istream stream(&amp;currentData); std::string data; std::getline(stream, data); boost::asio::async_read_until(socket, currentData, ' ', boost::bind(&amp;IrcConnection::onReceiveFinished, this, boost::asio::placeholders::error)); ios.dispatch(boost::bind(onM, data)); } }; void onMe(const std::string&amp; x) { std::cout &lt;&lt; "MESSAGE" &lt;&lt; std::endl; std::cout &lt;&lt; x &lt;&lt; std::endl; } int main() { boost::asio::io_service ios; std::string server = "irc.efnet.org"; int port = 6667; IrcConnection x(server, port, onMe, ios); x.connect(); while(!x.somethingHappened) { // } return 0; } </code></pre> <p>The program attempts to connect to irc.efnet.org and read until a space is sent and then spits that data out to the terminal. However I run this and all that is printed is the ip address of what I connected to and then the program does not terminate.</p> <p>What do I need to do to get my indented behavior?</p>
