GPQNV - Inquire Number of Definable View Table Entries

GPQNV (wstype, errind, number)

Note:

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

Purpose

Use GPQNV to inquire the number of definable view table entries for the specified workstation type.

The graPHIGS API returns data indicating the maximum number of views that can be defined in the view table for the specified workstation type. View zero is not included since it cannot be modified.

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
35: WORKSTATION HAS ONLY INPUT CAPABILITIES
548: SPECIFIED WORKSTATION TYPE CANNOT BE LOADED

number -- returned by the graPHIGS API, fullword integer

Number of definable view table entries. Entry 0 of the view table may not be changed.

Error Codes

None
