Comments

The undo level determines the number of automation operations that can be done within an automation container. The default value is DEF_AUTOMATION_UNDO_LEVEL [16]. If the undo level is set to 16, then each container associated with the automation handle has an undo level of 16.

To change the undo level call L_AutSetUndoLevel.

To undo an automation operation, call L_AutUndo.

To determine whether an automation operation can be undone, call L_AutCanUndo.

For information about grouping multiple operations into a single undo process, refer to L_AutAddUndoNode.
