[boost] Re: Lock unification [move]

The (proposed) move assignment philosophy is:

l1 = move(l2);

behaves as if:

atomic { if (l1.locked()) l1.unlock(); if (l2.locked()) { l2.unlock(); l1.lock(); } }

So in your example l2 would be unlocked, l1 would remain locked, and the underlying mutex lock count would be decremented by 1.

weird; the mutex association is not transferred along with "locked-ness"? Uh-oh: I think I just invoked the locked-ness monster. -- Dave Abrahams Boost Consulting http://www.boost-consulting.com
