Hello,

I've just discovered in old mails the meaning of the periodic and oneshot
modes available in rtl_setclockmode()
(especially this one:
http://www.realtimelinux.org/archives/rtl/20001/0240.html)

And it has triggered some questions in my spirit...

By default, in which mode RTLinux is ?

If I'm in periodic mode and on all the periodic tasks, the little period is
for example 10 ms, can I set in usleep() or nanosleep() time less than 10
ms...??? As the timer is programmed to interrupt every 10 ms only !???

Is there a difference between usleep() and nanosleep() (except the unit of
time of course ;-) ) ?

In periodic mode, when calling pthread_make_periodic_np( ), is start_time
parameter taken into account ? So that to optimize the little value of the
timer interrupt, we should set the same start_time for all the tasks ?

Finally there was quite a lot of questions... thanks in advance if someone can
clarify all that !

Bye.
