C++ (Cpp) IndexScanEnd Examples

Example #1

File: indexam.c Project: RingsC/postgres

/* ----------------
 *		index_endscan - end a scan
 * ----------------
 */
void
index_endscan(IndexScanDesc scan)
{
	SCAN_CHECKS;
	CHECK_SCAN_PROCEDURE(amendscan);

	/* Release any held pin on a heap page */
	if (BufferIsValid(scan->xs_cbuf))

		ReleaseBuffer(scan->xs_cbuf);
		scan->xs_cbuf = InvalidBuffer;
	}

	/* End the AM's scan */
	scan->indexRelation->rd_amroutine->amendscan(scan);

	/* Release index refcount acquired by index_beginscan */
	RelationDecrementReferenceCount(scan->indexRelation);

	if (scan->xs_temp_snap)
		UnregisterSnapshot(scan->xs_snapshot);

	/* Release the scan data structure itself */
	IndexScanEnd(scan);
}
