BACnetSetHook (FUN)¶

FUNCTION BACnetSetHook : IEC_BACNET_STATUS

Sets / registers a service hook

Registers a hook routine, which is the service application hook. The service application hook may override the default API processing of some BACnet service requests. A hook can be registered at any time. One hook procedure is registered per service. If the same service is hooked more than once (the hook is registered more than once for the same service), the new hook procedure replaces old one. A NULL procedure pointer cancels the hook.
