GPQAPF - Inquire Actual Pattern Facilities

GPQAPF (wsid, errind, maxrow, maxcol)

Purpose

Use GPQAPF to inquire the maximum pattern dimensions supported by the specified workstation.

The values the graPHIGS API returns indicate the maximum quantity of rows and columns that can be placed in a pattern array for the specified workstation.

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 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.

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

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.

Error Codes

None
