Remarks
Updates will be delivered via XblPresenceDevicePresenceChangedHandlers and XblPresenceTitlePresenceChangedHandlers. Note that the set of tracked users can be updated independent from the handlers. Register handlers with XblPresenceAddDevicePresenceChangedHandler and XblPresenceAddTitlePresenceChangedHandler. XSAPI creates and removes the Real-Time Activity (RTA) subscriptions for tracked users. Register title Presence handlers before you track users. Tracking is reference counted. Call XblPresenceStopTrackingUsers once for each successful call to this function for the same user. This function replaces the deprecatedXblPresenceSubscribeToDevicePresenceChange function. To replace the deprecated XblPresenceSubscribeToTitlePresenceChange function, also call XblPresenceTrackAdditionalTitles for titles other than the current title.
