[Boost-users] Deadlock with boost::asio::ip::tcp::iostream‏

1 Jul 2010

      Hi everyone,
I took the daytime example and add a request this iostream, and 
it starts deadlocking in windows environment. Is this the wrong way to do 
it?

int main(int argc, char* argv[])
{
  try
  {
    if (argc != 2)
    {
      std::cerr << "Usage: daytime_client <host>" << std::endl;
      return 1;
    }

    tcp::iostream s(argv[1], "daytime");
    s << "request";
    std::string line;
    std::getline(s, line);
    std::cout << line << std::endl;
  }
  catch (std::exception& e)
  {
    std::cout << "Exception: " << e.what() << std::endl;
  }

  return 0;
}

void 
server()
{
  try
  {
    boost::asio::io_service 
io_service;

    tcp::endpoint endpoint(tcp::v4(), 13);

tcp::acceptor acceptor(io_service, endpoint);

    for (;;)

{
      tcp::iostream stream;

acceptor.accept(*stream.rdbuf());
      std::string req;
      stream
...
...
req;
      stream << make_daytime_string();
    }
}
  catch (std::exception& e)
  {
    std::cerr << e.what() 
<< std::endl;
  }
}
