It depends on where originates the event which triggers the thread. If it originates from linux domain, there is no point waiting in primary mode, if it originates from Xenomai domain, the priority change will trigger a switch to secondary mode, so, you will loose the determinism of the response to the event. -- Gilles. _______________________________________________ Xenomai mailing list [email protected] http://www.xenomai.org/mailman/listinfo/xenomai
