Subject: futex: wake explicit / wait on multiple memory locations
Date: Wed, 23 Jul 2014 12:25:24 -0400	[thread overview]
Message-ID: <53CFE1F4.60705@adfin.com> (raw)

I'm using futexes to control scheduling for a userspace application with multiple queues. There's a global work queue and a specific pre-thread queue. And I would like to have a choice between waking up any thread or a specific thread.

Is there are mechanism in the futex API by which I can control which thread to wake up. Or alternatively a mechanism by which have a thread wait on multiple futex memory locations?

Thanks in advance,
- Milosz
