Abstract

The management of data access is facilitated. A loop only if changed locking facility is provided, in which reads and updates of the data being managed are permitted, unless an update to the data completes during the execution of the read or update routine. As long as an update to the data has not completed during a processor's execution of the read or update routine, access is permitted.
