Extensible event notificaton method and mechanism

An extensible event notification system detects certain events, and notifies requestor programs that have registered to receive such notification. The system includes a notification manager, multiple event notifier programs, multiple requester programs, a map, and a notification dictionary. When loaded by the notification manager, each event notifier program detects certain prescribed events. When advised by notifier programs of events, the notification manger consults the map to identify the requester programs registered for those events and any applicable notification parameters. Then the notification manger loads the requestor programs registered for those events, and notifies them of the occurrence of the events according to the applicable notification parameters.
