Remarks
Updates will be delivered via XblPresenceTitlePresenceChangedHandlers. Note that the set of tracked titles can be updated independent from the handlers. Title Presence updates are received only for users that you track with XblPresenceTrackUsers. Register a handler with XblPresenceAddTitlePresenceChangedHandler before you track users and titles. XSAPI creates and removes the Real-Time Activity (RTA) subscriptions. Tracking is reference counted. Call XblPresenceStopTrackingAdditionalTitles once for each successful call to this function for the same title. Together withXblPresenceTrackUsers, this function replaces the deprecated XblPresenceSubscribeToTitlePresenceChange function.
