Abstract
A mechanism for queuing a set of happened events in order of their occurrence and allowing for multiple occurrences to result in multiple processing iterations which mechanism maintains a multi-event table which is really a table of multi-event designations to be allocated to different processes upon request where the requesting processes assign a particular function with each multi-event entry and each of its own related event designations. The mechanism of the present invention maintains the state of such allocated multi-event entries in the multi-event table and signals the related or ('receiving') process that an event has happened within that set, and, if there are multiple events in the set which are happened, which of those events, occurred first by returning the events signature so that the particular system central processors assigned to execute those particular processes may then proceed with their execution and perform whatever processing is required for that particular event needing attention first.
