[Boost-users] Boost threads- how do I simultaneously check the lock on two or more mutexes?

boost::try_mutex M1, M2;
boost::try_mutex::scoped_try_lock lockx(M1, false);
boost::try_mutex::scoped_try_lock locky(M2, false);

I would like to be able to atomically check that at least one lock can be
made:

assert(lockx.try_lock() || locky.try_lock());

In Win32 I would use WaitForMultipleObjects.

Thanks in advance.
