Program a Irda port in Windows

Here is the first few lines of code I find in MSDN. It is a sample Irda socket server which should work fine in Windows CE.


SOCKET ServerSock,              // IR socket bound to the server
         ClientSock;              // IR socket bound to the client

  SOCKADDR_IRDA address = {AF_IRDA, 0, 0, 0, 0, "IRServer"};
  TCHAR szError[100];             // Error message string  

  // Create a socket bound to the server.
  if ((ServerSock = socket (AF_IRDA, SOCK_STREAM, 0)) == INVALID_SOCKET)
  {
    wsprintf (szError, TEXT("Allocating socket failed. Error: %d"),
              WSAGetLastError ());
    MessageBox (NULL, szError, TEXT("Error"), MB_OK);
    return FALSE;
  }

While I try to compile it and run in my notebook as my notebook also have a Irda port on it. It would appear an error with number 10093.

Do I make any mistakes? If so, what should I do so that I can program the Irda port on my PC to receive datas from other Irda devices?

The error 10093 is WSANOTINITIALISED, which means you have not called WSAStartup. You must call WSAStartup before using any WinSock functions and call WSACleanup in the end.
