INQUIRE MORE SIMULTANEOUS EVENTS (PHOP,*,*,*)

Purpose

Use Inquire More Simultaneous Events to inquire whether additional simultaneous events are waiting in the input queue.

The graPHIGS API returns a value indicating whether additional events are waiting that occurred from the same device trigger as the event previously in the current event report (CEV).

Your application can call this subroutine after your application issued the appropriate "Get" subroutine to obtain the current event from the CEV.

If the information is available, then the graPHIGS API sets the error indicator to zero and returns the value in the output parameter. If the information is unavailable, then the value returned in the output parameter is unpredictable and the graPHIGS API sets the error indicator to the following error:
