Event Notification Service (ENS) API

The Event Notification Service (ENS) is an alarm dispatcher that detects events on an alarm queue and sends notifications of these events to its subscribers. The ENS API allows programmers to modify publish-and-subscribe functions used by Calendar Server to perform functions such as subscribe to events, unsubscribe to events, and notify a subscriber of events. The ENS API's consists of these specific API's: Published API, Subscriber API, and Publish and Subscribe Dispatcher API.
