Re: [boost] [boost.thread] Atomic condition notify/wait on anothercondition

template <typename Lock, typename Pred> void condition::wait(Lock &lock, Pred while_cond) { while (while_cond) { old_wait(lock); } }

or something similar.

Does that make sense?

Good sense. It is so:

From http://www.boost.org/doc/html/condition.html

#2 template<typename ScopedLock, typename Pred> void wait(ScopedLock& lock, Pred pred); Requires: ScopedLock meets the ScopedLock requirements and the return from pred() is convertible to bool. Effects: As if: while (!pred()) wait(lock) Throws: lock_error if !lock.locked() Regards, Matt.
