[Xenomai-help] root_thread_exit in pSOS skin

I'm trying to use Xenomai over a Linux machine, in particular I'm trying to
emulate a pSOS system by using the demo satch (executable satch_uvm). I see
that root_thread_exit is never called.

How I have to do to get root_thread_exit called? I'd like to use this
function to remove a pipe created in root_thread_init.

Regards

root_thread_exit maps to __xeno_user_exit [1], and that should get
called by the UVM main function [2].

OK, but I  put a  xnprintf in root_thread_exit and I never saw this print. I
stop the emulation with CTRL+C.

Yeah, that correlates very well with the endless loop a few line above
in [2]...

In fact, I don't see how you should be able to install cleanup code this
way under the UVM. Maybe replacing the for loop with something like this
helps

while (uvm_thread_idle(&uvm_irqlock) >= 0)
	/* empty loop */;

but I'm leaving terra firma right now (never worked with the UVM).
