Could xenomai real time thread share the rt_mutex\rt_sem with the routine which is used as input argument of rt_alarm_create？

[孙世龙 via Xenomai]

Hi,

Could the main thread which has been shadowed(or
*xenomai real time thread* whose scheduling policy is *SCHED_FIFO*) *share
the rt_mutex\rt_sem*
*with the routine* which is used as input argument of *rt_alarm_create*？

Thank you for you attention to this matter.
Look forward to hearing from you.
