Creating and releasing cache areas

Creating

A new DAB cache area is created with the /START-DAB-CACHING command.

Releasing

The /STOP-DAB-CACHING command or, in exceptional cases, /FORCE-STOP-DAB-CACHING causes a DAB cache area to be released, with the following main action being performed:

With write or read/write caching, any data of the cache area to be released that is still in the cache is saved if necessary (unless the /FORCE-STOP-DAB-CACHING command has been issued). As a result, it may take some time to release the cache area using /STOP-DAB-CACHING.

When terminating the operating system (shutdown) DAB releases all existing cache areas.
