  • Use streams for continuous data that requires reliable delivery or prioritization.
  • Configure streams appropriately, balancing reliability and performance based on the specific data being transmitted.

DirectPlay Event Handling

DirectPlay uses an event-driven model to notify applications of asynchronous events. When an event occurs, DirectPlay generates an event notification and places it in an application’s event queue. The application can then retrieve the event notification and process the event.

There are several different types of events that can be generated by DirectPlay. These events include:

  • Connection events: These events indicate that a player has connected or disconnected from the session.
  • Message events: These events indicate that a player has sent a message to the session.
  • Lobby events: These events indicate that a player has joined or left the lobby.
  • Game events: These events indicate that a game event has occurred.

To handle DirectPlay events, an application must first register an event handler with DirectPlay. The event handler is a function that is called by DirectPlay when an event occurs. The event handler can then process the event and take appropriate action.


The following code shows how to register an event handler with DirectPlay:

“`cppHRESULT RegisterEventHandler(IDirectPlay8Client

pClient, PVOID pvUserContext)

DPEVENTHANDLER eventHandler; eventHandler.dwSize = sizeof(DPEVENTHANDLER); eventHandler.pfn = EventCallback; eventHandler.pvUserContext = pvUserContext; return pClient->RegisterEvent(NULL, &eventHandler);“`

The following code shows how to process an event in an event handler:

“`cppHRESULT EventCallback(PVOID pvUserContext, const DPNMSG_GENERIC


switch (pMsg->dwType) case DPN_MSGID_CREATE_PLAYER: // A new player has joined the session. break; case DPN_MSGID_DESTROY_PLAYER: // A player has left the session.

break; case DPN_MSGID_RECEIVE: // A player has sent a message to the session.

break; case DPN_MSGID_LOBBY_JOIN: // A player has joined the lobby. break; case DPN_MSGID_LOBBY_LEAVE: // A player has left the lobby.

An app on your PC needs the following feature: DirectPlay. This feature is typically used by games and other applications that require low-latency network communication. If you’re not sure whether or not your app needs DirectPlay, you can check with the app’s developer.
