Hi, based on the example http://www.boost.org/doc/libs/1_42_0/doc/html/boost_asio/tutorial/tutdaytime2.html , i wanna to separate the part of the code that open de connection , and the part of the code that write a string over the socket, the problem is , that i have no clear how to share the information of the socket between the both fuctions. In this code below i suppose that listen fucion must to return the socket information, but what data type must the function listen() return???
thanks so much in advance

void Agent::listen()
{

try
{
    printf("SERVER A STARTED UDPsk \n");
    boost::asio::io_service io_service;

    tcp::acceptor acceptor(io_service, tcp::endpoint(tcp::v4(), 7777));

    //for (;;)
    {
      tcp::socket socket(io_service);
      acceptor.accept(socket);

    }
}
catch (std::exception& e)
{
    std::cerr << e.what() << std::endl;
}
}

void Agent::write()
{

try
{
      std::string message = "mymsg";
      boost::system::error_code ignored_error;
      boost::asio::write(socket, boost::asio::buffer(message),
          boost::asio::transfer_all(), ignored_error);
    sleep(1);
    socket.close();
    return;
    }
}
catch (std::exception& e)
{
    std::cerr << e.what() << std::endl;
}
}
