ABSTRACT:
An event notification facility includes an interface by which programs register for notification of an event. When registering, each program identifies a type of event and a mechanism by which the program is to be notified if and when an event of the identified type occurs. At the program's option, it can request that it be notified "last," i.e. after all other programs have been notified of the event. The event notification facility also includes a means for storing the registration requests and for associating each registration request with a type of event. Once a program is registered to be notified of an event last, the event notification facility rejects all other requests from programs to be notified of the same event last, however preferably other programs can still register for notification of the event. Finally, the event notification facility includes a means for notifying each registered program when the event occurs.
