CUSTOMIZED AND VERSATILE EVENT MONITOR WITHIN EVENT MANAGEMENT SERVICES OF A COMPUTER SYSTEM

A computer operating system manages different types of events. An application program or another part of the operating system defines an event monitor to monitor one or more types of events. The definition also specifies a combination of occurrences of the one or more types of events required to satisfy the event monitor. When each of the monitored events occurs, the event monitor is signalled and stores the event signal. When the event monitor has stored signals which satisfy the event monitor, the event monitor can notify an event handler (pursuant to a standing or subsequent inquiry by the event handler). Then, the event handler can access the stored event signals.
