Subject: [Xenomai] How to use timer services without switching to secondary mode?
Date: Thu, 23 Jul 2015 10:07:40 +0200 [thread overview]
Message-ID: <00a901d0c51e$a62a1190$f27e34b0$@gmail.com> (raw)
Hello list!
I have to write a Xenomai 2.6.4 thread that is activated upon the
expiration of a (periodic) timer. It is not clear to me how to do that
without switching to secondary mode.
I would like to stick with the POSIX skin but, in my understanding, with
the POSIX skin, using the `timer_create()` and `timer_settime()` I will
switch to secondary mode on timer expiration, because a signal is
generated by that event. Is it correct?
On the other hand, the switching to secondary mode does not happens
using the Native Xenomai API, i.e. `rt_alarm_create()` and
`rt_alarm_start()`. Am I wrong?
What are the options available for that purpose? Should I use the
`pthread_make_periodic_np()` instead? What are the differences wrt
`timer_*` calls?
Thank you for the support and kind regards,
Giorgio B.
