GPQCPF - Inquire Color Processing Facilities

GPQCPF (wstype, errind, number, npred)

Note:

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

Purpose

Use GPQCPF to inquire the color processing mode table facilities supported by the specified workstation.

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 color processing mode table entries. Entry 0 of the color processing table may not be changed.

npred -- returned by the graPHIGS API, fullword integer

Number of predefined color processing mode table entries.

Error Codes

None
