Defined in header <condition_variable>
class condition_variable_any;		(since C++11)

The condition_variable_any class manages a list of threads that are waiting until another thread notifies one or all of the waiting threads that they may proceed, until a timeout expires, or until a spurious wakeup occurs. Any thread that intends to wait on std::condition_variable_any has to acquire a lock first. The wait operation atomically releases the lock and suspends the execution of the thread. When the thread is awakened, the lock is reacquired.

If the lock is std::unique_lock, std::condition_variable may provide better performance.

The class std::condition_variable_any is a standard-layout class. It is not copy-constructible, move-constructible, copy-assignable, or move-assignable.
