[Xenomai-help] Signals

[Kent Borg <kentborg@domain.hid>]

Thanks for the news that gdb should just work.

Now I am wondering about signals.  I want to be able to send a regular
Linux signal to a userland realtime process.  Do I use the regular
signal() to install a signal handler?  When would I use
rt_task_catch() and rt_task_notify()?

What about multiple threads?  I have 2 threads running.  It seems that
the thread that called signal() is the one landing in the handler
routine.  I would like to set some flags for the second thread to see,
so it can cleanup things before quiting, but it seems that my second
thread isn't running after I send the signal.  I also think I am
corrupting something, because if I set up a loop that launches and
kills my program, my machine freezes up after a dozen cycles.  I
commented out most of my guts and it still freezes up.


Thanks,
