Subject: [Xenomai-help] Sharing of access to RT_MUTEX, RT_QUEUE, and RT_TASK
Date: Mon, 30 Jan 2012 22:40:03 -0800 (PST)	[thread overview]
Message-ID: <1327992003.514524717@domain.hid> (raw)

I'm working on an application where it would be convenient for several tasks within the same process to share access to single descriptors for mutexes, queues, and tasks, rather than each task having to separately bind to each one and keep its own RT_MUTEX/RT_QUEUE/RT_TASK.

The documentation doesn't seem to speak to this issue, and I haven't been able to find a definitive answer through searches. Can anyone clarify whether or not this will lead to problems, e.g. task A is in the midst of locking a mutex when task B starts trying to obtain a lock itself, and bad results occur?

Thanks,
    Doug Brunner
