Type: char\*

## Remarks

If this function is invoked, Multiplayer Manager sends invites to the selected players when the user confirms the player selection in the standard XBOX UI. If a selected player accepts the invite, the title is notified. For GDK-based games, the title is notified by invoking the callback function specified when the [XGameInviteRegisterForEvent](/reference/system/xgameinvite/functions/xgameinviteregisterforevent) function was invoked. For games based on other platforms, the title is activated. For more information, see [Receiving invites](/services/xbox-services/multiplayer/invites/how-to/live-invites-receive).
