Detailed Description

A condition variable.

Delegates to ThreadDriver for the actual platform primitive. wait() must be called with lock already held; signal() wakes every waiter (see ThreadDriver::signalCond - there is no single-waiter wake across backends).

signal()

void Cond::signal

(

)

Wakes every thread currently blocked in wait() on this condition variable.

wait()

void Cond::wait

(

Mutex &

lock

)

Unlocks lock and blocks until signal() is called, then reacquires lock before returning.

lock must be locked by the calling thread on entry. Since signal() wakes every waiter, callers must re-check their wake condition in a loop.
