GPQIMV - Inquire Image Mapping on View

GPQIMV (wsid, view, start, number, errind, totnum, limid)

Note:

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

Purpose

Use GPQIMV to inquire the current image mappings on the specified view.

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.

view -- specified by user, fullword integer

View index (>=0)

start -- specified by user, fullword integer

Starting member of the list of defined image mappings (>=1)

number -- specified by user, fullword integer

Number of image mappings 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
59: VIEW INDEX VALUE < ZERO
323: VIEW INDEX EXCEEDS VIEW TABLE CAPACITY
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 image mappings on the view.

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

List of image mapping identifiers on the view.

None
