GPQPAF - Inquire Pattern Facilities

GPQPAF (wstype, errind, maxrow, maxcol, indexes)

Note:

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

Purpose

Use GPQPAF to inquire the pattern facilities for the specified workstation type.

The graPHIGS API returns the maximum pattern array dimensions, including the maximum number of rows (maxrow) and columns (maxcol) and the number of predefined pattern indexes (indexes) for 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

maxrow -- returned by the graPHIGS API, fullword integer

Maximum number of rows in the pattern array.

maxcol -- returned by the graPHIGS API, fullword integer

Maximum number of columns in the pattern array.

indexes -- returned by the graPHIGS API, fullword integer

Number of predefined pattern indexes.

Error Codes
