This function joins the Xbox user specified in user to the lobby session specified in handleId. The activity handle for the lobby session is typically retrieved either from a game invite or from the HandleId value of another user's XblMultiplayerActivityDetails, by calling XblMultiplayerGetActivitiesForUsersAsync. For more information about multiplayer activities, see Activities.
The result of this function is delivered as a multiplayer event with an event type set to XblMultiplayerEventType::JoinLobbyCompleted. You can call XblMultiplayerManagerDoWork to retrieve multiplayer events.
When attempting to join a lobby session, the service returns HTTP_E_STATUS_BAD_REQUEST if the server is full.
After joining, you can set the properties for the lobby session by calling XblMultiplayerManagerLobbySessionSetSynchronizedProperties, or you can set the host for the lobby session by calling XblMultiplayerManagerLobbySessionSetSynchronizedHost if the lobby session doesn't already have a host.
You can also send an invite to another user by calling either XblMultiplayerManagerLobbySessionInviteUsers or XblMultiplayerManagerLobbySessionInviteFriends. If you don't need a lobby session, and if you haven't added local users by calling XblMultiplayerManagerLobbySessionAddLocalUser, you can instead call XblMultiplayerManagerJoinGame and specify the list of users to join the game.
