Xenomai POSIX messages queues can only be used by Xenomai tasks, but Xenomai tasks do not switch to secondary mode when using POSIX messages queues. Note that when using the POSIX skin, all tasks are Xenomai tasks, the SCHED_OTHER policy being reserved to non-realtime task. Another solution is to use the native skin message pipe services, described here: http://www.xenomai.org/documentation/trunk/html/api/group__pipe.html -- Gilles Chanteperdrix
