GPQWD - Inquire Workstation Display Classification

GPQWD (wstype, errind, type)

Note:

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

Purpose

Use GPQWD to inquire the display category for the specified workstation type.

The graPHIGS API returns a value indicating whether the workstation type utilizes vector, raster, or other types of display technology.

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

Error indicator. If the error indicator is zero, the request has been completed. Otherwise, one of the following errors exists:

23: SPECIFIED WORKSTATION TYPE DOES NOT EXIST
548: SPECIFIED WORKSTATION TYPE CANNOT BE LOADED

type -- returned by the graPHIGS API, fullword integer

Display type (1=VECTOR, 2=RASTER, 3=OTHERS )

Error Codes
