EVT_BACNET_UTCTIMESYNC (STRUCT)¶
TYPE EVT_BACNET_UTCTIMESYNC : STRUCT
The UTC TimeSynchronization service hook
This is the type declaration for the UTC Time Synchronization service application hook. This hook allows a BACnet application to override the default BACnet processing of a Time Synchronization service request. The hook is given all of the parameters of a service request, and is responsible for all error checking (address correctness, value correctness and so forth). A pointer to the routine is registered with the BACnet server by BACnetSetHook. A hook can be registered by the registering API routine at any time. One hook procedure is registered per service. If a hook is registered more than once for the same service, the new hook procedure replaces old one. A 0 procedure pointer can be used to deregister the hook. Since this is an unconfirmed service, no response is expected. A Time Synchronization hook must complete its service request processing only by returning its Return Value.
- InOut:
- Name - Type - Comment - pCBStatus- POINTER TO IEC_BACNET_CB_STATUS - CB-Status returned for the event. “Default” processes the standard APIs reaction, which needs no additional Callback-Signalling. - phTransaction- POINTER TO BYTE - This is the Transaction State Machine (TSM) handle for the current service request. It is generated by the BACnet API and is the first parameter given to the Hook- Completion functions. - sourceAddress- POINTER TO IEC_BACNET_ADDRESS - This is the MAC address of the BACnet addressed device from which the request has been sent. - destinationAddress- POINTER TO IEC_BACNET_ADDRESS - This is the MAC address of the device constructed by the application which has received the request. - pServiceInfo- POINTER TO IEC_BACNET_TIME_SYNC_INFO - A pointer to the service information data structure. The fields of this data structure include Date Time information.
