5157,Assign native socket problem,a.pacek@…,chris_kohlhoff,"Hi

I'm trying to duplicate accepted/opened socket and pass them to other process.
It works fine under linux. But under Windows I can't assign
this native socket to boost::asio::ip::tcp::socket.
When I try to assign opened native socket to boost socket object
s.assign(boost::asio::ip::tcp::v4(), socketDup)
throws me exception: ""The parameter is incorrect"".
Even if I try to duplicate socket and use them in the same process.
I still got this exception.

The line inside boost throws this exception:
boost_1_45_0\boost\asio\detail\impl\win_iocp_io_service.ipp:

{{{
boost::system::error_code win_iocp_io_service::register_handle(
    HANDLE handle, boost::system::error_code& ec)
{
  if (::CreateIoCompletionPort(handle, iocp_.handle, 0, 0) == 0)	//this function failed
  {
    DWORD last_error = ::GetLastError();
    ec = boost::system::error_code(last_error,
        boost::asio::error::get_system_category());
  }
  else
  {
    ec = boost::system::error_code();
  }
  return ec;
}

}}}

I'm using: VC++ 2008 / Win7

What am I doing wrong?
How can I resolve this problem?
Thanks for help.




Example code:



{{{
boost::asio::io_service io_service;
tcp::acceptor acceptor(io_service, tcp::endpoint(tcp::v4(), m_nPort));

std::cout << ""Waiting for connection..."" << std::endl;

tcp::socket socket(io_service);
acceptor.accept(socket);
std::cout << ""connection accepted"" << std::endl;

#ifdef _WIN32
WSAPROTOCOL_INFO pi;
WSADuplicateSocket(socket.native(), get_current_process_id(), &pi);
SOCKET socketDup = WSASocket(pi.iAddressFamily/*AF_INET*/, pi.iSocketType/*SOCK_STREAM*/,
pi.iProtocol/*IPPROTO_TCP*/, &pi, 0, 0);
char sText[] = ""I can use my duplicated socket via WinApi!\r\n"";
int nRet = send(socketDup, sText, strlen(sText), 0);
#else
	//linux
	int socketDup = dup(socket.native());
#endif

try
{
	tcp::socket s(io_service);
	s.assign(boost::asio::ip::tcp::v4(), socketDup); //this throws exception under Windows
	//I can't use my socket via boost lib
	s.send(boost::asio::buffer(""Not work\r\n""));
}
catch(std::exception &e)
{
	std::cerr << e.what() << std::endl; //""The parameter is incorrect"" exception
}
