GPQDV - Inquire Deferral and Update State Values

GPQDV (wsid, errind, defer, modif, dissurf, dstat)

Note:

This subroutine is a Workstation State List (WSL) inquiry. For an overview, see "WSL Inquiries"

Purpose

Use GPQDV to inquire the current deferral and update state values for the specified workstation.

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

Parameters

wsid -- specified by user, fullword integer

Workstation identifier.

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:

25: SPECIFIED WORKSTATION DOES NOT EXIST
35: WORKSTATION HAS ONLY INPUT CAPABILITIES

defer -- returned by the graPHIGS API, fullword integer

Deferral mode (1=ASAP, 2=BNIG, 3=BNIL, 4=ASTI, 5=WAIT )

modif -- returned by the graPHIGS API, fullword integer

Modification mode (1=NO_IMMEDIATE_VISUAL_EFFECT, 2=UPDATE_WITHOUT_REGNERATION, 3=QUICK_UPDATE )

dissurf -- returned by the graPHIGS API, fullword integer

Display surface empty (1=NOT_EMPTY, 2=IS_EMPTY )

dstat -- returned by the graPHIGS API, fullword integer

Display status (1=CORRECT, 2=DEFERRED, 3=SIMULATED )

Error Codes

None
