GPQDCF - Inquire Depth Cue Facilities

GPQDCF (wstype, errind, number, npred)

Note:

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

Purpose

Use GPQDCF to inquire the depth cue facilities 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 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 -- specified by user, 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 depth cue table entries. Entry 0 of the depth cue table may not be changed.

npred -- returned by the graPHIGS API, fullword integer

Number of predefined depth cue indexes.

Error Codes

None
