EVT_BACNET_SUBSCRIBE_COV_PROP_MUL (STRUCT)¶

TYPE EVT_BACNET_SUBSCRIBE_COV_PROP_MUL : STRUCT

The SubscribeCOVPropertyMultiple service hook.

The Subscribe COV Property Multiple hook must complete its service request processing by using one of the transaction completion API routines: ::BACnetSubscribeCovPropMultipleErrorCbCompletion, ::BACnetSrvcResponseCbCompletion, ::BACnetSrvcAbortCbCompletion, ::BACnetSrvcErrorCbCompletion, ::BACnetSrvcIgnoreCbCompletion, or ::BACnetSrvcRejectCbCompletion. Hooks can access the local Properties maintained in the API database by using the ::BACnetStorePropertyInstance / ::BACnetRetrievePropertyInstance routines. A hook can choose not to override the default API processing of a service request by returning the value ::CB_STATUS_DEFAULT.

Return: IEC_BACNET_CB_STATUS
