GPQRCM - Inquire Available Rendering Color Models

GPQRCM (wstype, start, number, errind, totnum, model)

Note:

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

Purpose

Use GPQRCM to inquire a list of available rendering color models for the specified workstation type.

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 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 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.

start -- specified by user, fullword integer

Starting member of the list of available rendering color models (>=1)

number -- specified by user, fullword integer

Number of rendering color models 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:
23
SPECIFIED WORKSTATION TYPE DOES NOT EXIST
35
WORKSTATION HAS ONLY INPUT CAPABILITIES
538
START VALUE < ONE
539
REQUESTED NUMBER < ZERO
543
START EXCEEDS DATA EXTENT. TOTAL NUMBER AVAILABLE RETURNED
548
SPECIFIED WORKSTATION TYPE CANNOT BE LOADED

totnum -- returned by the graPHIGS API, fullword integer

Total number of available rendering color models.

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

List of rendering color models ( 1=RGB_NORMAL, 2=RGB_B_ONLY )

Error Codes

None
