Example UDP async server stops on error...

[Micah Quinn <micah.quinn@…>]

In the boost::asio UDP async server example, if a recv_from error occurs, the server stops receiving completely. The code in question is in the "start_receive()" function:

void handle_receive(const boost::system::error_code& error,
      std::size_t /*bytes_transferred*/)
  {
    if (!error || error == boost::asio::error::message_size)
    {
....
      start_receive();
    }
  }

Should instead be (with start_receive() moved outside the error check):

void handle_receive(const boost::system::error_code& error,
      std::size_t /*bytes_transferred*/)
  {
    if (!error || error == boost::asio::error::message_size)
    {
....
    }
    start_receive();
  }
