RE: reset method

John,

Let me understand your objective better. You want that while a process is being killed/reset, there be some way of telling which is happening? For example, if the process itself catches sc_kill_exception, and wants to do one kind of cleanup or another based on whether it is getting killed or reset. Is that the objective?

Thanks,

Bishnupriya,

It's nice to be able to catch and handle kills and resets, but I don't think it's important enough to justify anything but the simplest mechanism. I would have thought that most of the time kills and resets could be handled in the same way.

I was musing on some other way of telling whether the process had been killed or reset, and method terminated() came to mind, but presumably a killed process would not get terminated until the exception was caught by the kernel, so that's no good.

I am arguing semantics here, but if we have a common exception, that exception does not necessarily terminate the process, because it is being used for both reset() and kill(): reset() does not leave the process terminated. So having class sc_kill_exception: public sc_reset_exception makes more sense to me, with the sc_reset_exception actually doing the work of unwinding the stack. Does that work?

If you're going to throw an exception anyhow, then I would prefer the sc_reset_exception solution over adding another member method.

John,

Yes reset() throws an sc_kill_exception.

It is a good idea to distinguish reset from kill by using the exception. I suggest a member method in the sc_kill_exception class - "bool reset()" - or perhaps have sc_reet_exception that derives from sc_kill_exception?

WDYT?

Thanks,
