Remarks

This function submits a matchmaking request for the lobby session to Multiplayer Manager (MPM). Before you can use this function, you must first configure hoppers in the service configuration for your title. A hopper defines the rules that SmartMatch uses to match players. For more information about hoppers, see Matchmaking overview. If a lobby session doesn't exist, likely because XblMultiplayerManagerInitialize wasn't called, or if local users weren't added to the lobby session before calling this function, an error occurs. An error also occurs if matchmaking is already in progress.
The result of this function is delivered as a multiplayer event with an event type set to XblMultiplayerEventType::FindMatchCompleted. You can call XblMultiplayerManagerDoWork to retrieve multiplayer events.
