GPQVR - Inquire Set of View Which Contain Root

GPQVR (wsid, strid, start, number, errind, totnum, view)

Note:

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

Purpose

Use GPQVR to inquire a list of views which contains the specified structure in the currently selected structure store as their roots.

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 error indicator is 543 (the start value exceeds the extent of the available data), then only the total number (totnum) parameter is set. 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.

strid -- specified by user, fullword integer

Structure identifier.

start -- specified by user, fullword integer

Starting member of the list of view indexes (>=1)

number -- specified by user, fullword integer

Number of view indexes requested (>=0)

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
122: STRUCTURE IDENTIFIER DOES NOT EXIST
215: SPECIFIED RESOURCES DO NOT EXIST ON THE SAME NUCLEUS
227: STRUCTURE STORE IS NOT SELECTED
538: START VALUE < ONE
539: REQUESTED NUMBER < ZERO
543: START EXCEEDS DATA EXTENT. TOTAL NUMBER AVAILABLE RETURNED

totnum -- returned by the graPHIGS API, fullword integer

Total number of views which contain the root.

view -- returned by the graPHIGS API, array of fullword integers

List of view indexes which contain the root.
