## Remarks

Call this function to get more information about multiplayer events returned by [xblMultiplayerManagerDoWork](/reference/live/xsapi-c/multiplayer_manager_c/functions/xblmultiplayermanagerdowork) for which the `EventType` member of the [XblMultiplayerEvent](/reference/live/xsapi-c/multiplayer_manager_c/structs/xblmultiplayerevent) for a multiplayer event is set to either `XblMultiplayerEventType::MemberPropertyChanged` or `XblMultiplayerEventType::SessionPropertyChanged`. <br />The event arguments handle for a multiplayer event can be retrieved from the `EventArgsHandle` member of the [XblMultiplayerEvent](/reference/live/xsapi-c/multiplayer_manager_c/structs/xblmultiplayerevent) structure for that multiplayer event.  <br />For more information about multiplayer events, see [Multiplayer Manager API overview](/services/xbox-services/multiplayer/mpm/concepts/live-multiplayer-manager-api-overview).
