Abstract

A method is described for communicating event information from an active application in a multitasking environment to another application that is not currently active. Event information is primarily concerned with completion of tasks within an application. A multitasking operating system allows multiple applications to run concurrently at different priorities. A problem occurs when the active application wants to notify another (not active) application that an event has occurred. The notification of an event completion may cause the notified application to dispatch a new process. This new process can either be higher or lower in priority than the last process dispatched for that application.
