EVT_BACNET_UNCONFEVENTNOTIFICATION (STRUCT)

TYPE EVT_BACNET_UNCONFEVENTNOTIFICATION : STRUCT

Receives unconfirmed Intrinsic Alarm and Event notification requests.

This is the type declaration for the Unconfirmed Event Notification service application hook. This hook allows a BACnet application to override the default processing of a Unconfirmed Event service request. This hook is given all of the parameters of a service request, and is responsible for all error checking (object existence, correspondence of parameters and any other service parameter given). A pointer to the routine is registered by BACnetSetHook. A hook can be registered 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 the old one. A NULL procedure pointer can be used to unregister the hook.
