GPQCNA - Inquire Conflicting Structures in Network in Archive

GPQCNA (arid, strid, source, start, number, errind, totnum, istrid)

Note:

This subroutine is an Archive inquiry. For an overview, see "Archive Inquiries"

Purpose

Use GPQCNA to inquire a list of structure identifiers from a specified structure network that exists in both the currently selected structure store and the specified open archive file.

The value for the source determines whether the structure network originates from the currently selected structure store or from the archive file.

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

arid -- specified by user, fullword integer

Archive file identifier.

strid -- specified by user, fullword integer

Structure identifier of the root structure.

source -- specified by user, fullword integer

The source of the structure network to be searched:
Value Meaning
1 Currently selected structure store
2 Archive file

start -- specified by user, fullword integer

The starting member of the list of structure identifiers (>=1)

number -- specified by user, fullword integer

Number of entries 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:
7
FUNCTION REQUIRES STATE AROP
12
FUNCTION REQUIRES STATE SSSL
122
STRUCTURE IDENTIFIER DOES NOT EXIST
135
VALUE OF SOURCE IS INVALID
220
SPECIFIED ARCHIVE FILE DOES NOT EXIST
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 conflicting structures in the network.

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

List of conflicting structure identifiers.

Error Codes

None
