[Xenomai-main] Exiting the Xenomai emulation

[Fabrice TOMASI]

            Hi,

   Just a question about how to exit the emulation running on top of 
Xenomai (Xenomai is configured for the POSIX layer). In our project, 
we've got a constant which tells how long the emulation/simulation has 
to run before exiting. For instance, the test of the elapsed time is 
done in a custom interruption thread started with xnpod_start_timer(). 
So, this "thread" belongs to isvc0. What we want to do is to make 
Xenomai calls the posix_cleanup_application() function when exiting, 
which suppose that all Xenomai processes are killed (posix_thread_count 
must be 0).
   The problem is xnpod_shutdown() is called from the custom 
interruption thread but isvc0 can't shutdown itself because it is in an 
interrupt context. Hence the counter posix_thread_count can never be set 
to 0.
   So, we tried to solve this problem using another thread which is 
created at the very beginning of the emulation. This thread goes to 
sleep until the custom interruption thread resume it at the end of the 
emulation. Now, the xnpod_shutdown() can be called in this thread and 
the emulation exits normally.
   What do you think of this solution ? Is it good or is it wrong ? Is 
there a better way to solve this problem ?

      Thanks for help
