sys.abort_task() can be called from anywhere as long as a CISAM task is in progress.

Example:

Description:

sys.abort_task() aborts a CISAM transaction. sys.abort_task() calls isrollback(). You should read and understand the isrollback() documentation in the CISAM manuals.

Bugs/Features/Comments:

No Nested transactions.

Beware of ENORMOUS log files.

4C will eventually need to accomodate other file systems that allow transaction processing. A new more general call will probably replace sys.abort_task().
