An extensible event notification system detects certain events (106), and notifies requestor programs (108a-c) that have registered to receive such notification. The system includes a notification manager (102), multiple eve nt notifier programs (104a-c), multiple requestor programs (108a-c), a map (110 ), and a notification dictionary (112). When loaded by the notification manager (102), each event notifier program (104a-c) detecs certain prescribed events (106). When advised by notifier programs(104a-c)of events(106), the notification manager(102)consults the map (110)to identify the requester programs (108a-c)registered for those events (106) and any applicable notification parameters. Then the notification manager(102) loads the requestor programs (108a-c) registered for those events (106), and notifies them of the occurrence of the events (106) according to the applicable notification parameters (112). |
