The graPHIGS Programming Interface: ISO PHIGS Subroutine Reference

GET VALUATOR (PHOP,WSOP,*,*)

Purpose

Use Get Valuator to retrieve a valuator input value from the current event report. The graPHIGS API does not remove the event from the current event report until the next invocation of the Await Event subroutine call.

The graPHIGS API returns a value within the range found in the valuator data record at the time the device was set to event mode.

The graPHIGS API identified the device to which this value corresponds on the previous invocation of Await Event.
