    class condition_variable;
    		 (seit C++11)

    Die condition_variable Klasse ist ein grundlegendes Synchronisierungsmittel das verwendet werden kann, um einen Thread oder mehrere Threads gleichzeitig zu blockieren, bis:

    • eine Benachrichtigung von einem anderen Thread empfangen wird
    • es zu einer Zeitüberschreitung kommt, oder
    • ein spurious wakeup auftritt

    Jeder Thread, der auf einer std::condition_variable warten möchte, muss zuerst ein std::unique_lock erwerben. Die wait-Operationen geben den gelockten Mutex atomar frei und pausieren den aktuellen Thread. Wenn die condition-Variable benachrichtigt wird, wird der Thread geweckt, und der Mutex wieder gelockt.

    Die Klasse std::condition_variable ist ein StandardLayoutType. Sie ist nicht CopyConstructible, MoveConstructible, CopyAssignable, MoveAssignable.
