Is there any singal, callback, API or any Dakota indicator to signal process finish, fail or exception?

[iaae]

I have carefully reviewed the manual and documentation, but I couldn't find any direct signal, callback or indicator that notifies when the Dakota process finishes or fails. Most of the examples and drivers seem to depend on the system process finishing signal and then review the result output or tabular table.

Currently, we just log the Dakota process thread and monitor the exit code to begin the next task.

Do you have any ideas, suggestions or information that could help with this? Thanks.
