The graPHIGS Programming Interface : Subroutine Reference

GPQVF - Inquire View Facilities

GPQVF (wstype, errind, shield)

Note:

This subroutine is a Workstation Description Table (WDT) inquiry. For an overview, see "WDT Inquiries"

Purpose

Use GPQVF to inquire whether shielding is available for the specified workstation type.

The graPHIGS API returns data indicating whether shielding is available on the specified workstation type.

If the information is available, then the graPHIGS API sets the error indicator to zero and returns the values in the output parameter. If the inquired information is unavailable, then the error indicator ( errind) contains the error number indicating the reason, and the values returned in the output parameter are unpredictable.

Parameters

wstype -- specified by user, 8-byte character string

Workstation type.

errind -- returned by the graPHIGS API, fullword integer

548

shield -- returned by the graPHIGS API, fullword integer
