GPQWST - Inquire List of Available Workstation Types

GPQWST (start, number, errind, maxopen, nwstype, wstype)

Purpose

Use GPQWST to inquire a list of available generic workstation types that can be open on a nucleus with nucleus identifier=1.

The graPHIGS API returns a value indicating the number of workstation types and a list of those types.

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 error indicator is 543 (the start value exceeds the extent of the available data), then only the total number (totnum) parameter is set. 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

start -- specified by user, fullword integer

Starting member of the list of workstation types (>=1)

number -- specified by user, fullword integer

Number of workstation types requested (>=0)

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:
202
SPECIFIED NUCLEUS DOES NOT EXIST
538
START VALUE < ONE
539
REQUESTED NUMBER < ZERO
543
START EXCEEDS DATA EXTENT. TOTAL NUMBER AVAILABLE RETURNED

maxopen -- returned by the graPHIGS API, fullword integer

Maximum number of workstations to which a structure store can be simultaneously associated.

nwstype -- returned by the graPHIGS API, fullword integer

Total number of available generic workstation types.

wstype -- returned by the graPHIGS API, array of 8-byte character strings

List of available generic workstation types. The output array must be large enough to contain the requested data.

Error Codes
