GPQAVF - Inquire Actual View Facilities

GPQAVF (wsid, errind, shield)

Purpose

Use GPQAVF to inquire the availability of view shielding 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

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

shield -- returned by the graPHIGS API, fullword integer
