    [Bearbeiten]Zustand Variablen

    A condition variable is a synchronization primitive that allows multiple threads to communicate with eachother. It allows some number of threads to wait (possibly with a timeout) for notification from another thread that they may proceed. A condition variable is always associated with a mutex.

    definiert in Header <condition_variable>
    (C++11)
    		 provides a condition variable associated with a std::unique_lock
    (Klasse)
    (C++11)
    		 provides a condition variable associated with any lock type
    (Klasse)
    (C++11)
    		 schedules a call to notify_all to be invoked when this thread is completely finished
    (Funktion)
    (C++11)
    		 lists the possible results of timed waits on condition variables
    (enum)

    [Bearbeiten]Futures

    Die Standardbibliothek bietet Möglichkeiten, Rückgabewerte von asynchronen Tasks (d. h. Funktionen, die in separaten Threads gestartet werden) zu erhalten, und Ausnahmen abzufangen, die von diesen Tasks ausgelöst werden. Diese Werte werden in einem gemeinsamen Zustandsobjekt gehalten, in welches der asynchrone Task seinen Rückgabewert schreiben oder eine Ausnahme speichern kann, und das von anderen Threads, die Instanzen oder Verweise dieses gemeinsamen Zustandsobjekts besitzen std::future oder std::shared_future, untersucht, abgewartet oder anderweitig manipuliert werden kann.

    definiert in Header <future>
    (C++11)
    speichert einen Wert für asynchrone Abruf

    stores a value for asynchronous retrieval
