Re: [Xenomai-help] how to stop a runaway task

Meanwhile i got my sample code running:
When removing the printf it works fine.
So for me it looks like a problem when a task is switched to secondary
domain.
Is there a way to force a thread to switch back to primary domain?

Now i unsuccesfully tried to get a posix skin variant running.
(my real app is based on pthread)
Since i only can use signals to suspend a posix thread (correct me if
i'm wrong) i run in the same problem with the secondary domain.

Is there a way to switch back to primary domain in posix skin?

Do i have a chance to do this with pthread or do i have to rewrite my
code using rt_task* calls?

Thanks for your help, regards

Carsten
