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;
  }
}
