GPQCEV - Inquire Current Event

Note:

This subroutine is a graPHIGS API State List (PSL) inquiry. For an overview, see "PSL Inquiries"

Purpose

Use GPQCEV to inquire information about the current event report.

When the current event report is empty, the graPHIGS API returns a zero for the event class parameter and major/minor code parameters are not set. Otherwise, the graPHIGS API returns an event class of the event in the current event report to the event class parameter.

The details of the possible event classes and meanings of their major and minor codes are shown in The graPHIGS Programming Interface: Technical Reference
