GPQCNC - Inquire List of Connected Nuclei

GPQCNC (start, number, errind, totnum, ncid)

Note:

This subroutine is a graPHIGS API State List (PSL) inquiry. For an overview, see "PSL Inquiries"

Purpose

Use GPQCNC to inquire the nuclei that are connected to the application process (shell)

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 in the list of connected nuclei (>=1)

number -- specified by user, fullword integer

Number of nucleus identifiers 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:

538: START VALUE < ONE
539: REQUESTED NUMBER < ZERO
543: START EXCEEDS DATA EXTENT. TOTAL NUMBER AVAILABLE RETURNED

totnum -- returned by the graPHIGS API, fullword integer

Total number of connected nuclei.

ncid -- returned by the graPHIGS API, array of fullword integers

List of nucleus identifiers connected to the application process (shell)

Error Codes

None
