GPQANV - Inquire Actual Number of Definable View Table Entries

GPQANV (wsid, errind, number)

Purpose

Use GPQANV to inquire the quantity of definable view table entries for the specified workstation. (View zero is not included because it cannot be modified)

The number the graPHIGS API returns indicates the quantity of view table entries that can be defined 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

number -- returned by the graPHIGS API, fullword integer

Number of definable view table indexes. (Entry 0 may not be changed)

Error Codes

None
