How do I cancel long running operation when a couroutine is cancelled ?

I know I can somehow use isActive, but here I would want to provide some kind of onCancelled callback.
(here when I do cancel process is still present when doing ps aux)

thanks, is there any high level api for this ?

+ is it ok to launch coroutines inside suspend...Coroutine blocks ?

The API is simple

suspendCancellableCoroutine {
            it.invokeOnCancellation { cancel the job }
            it.resume(return result)
        }

this is to wrap blocking call into a coroutine that can be cancelled.
