Lädt atomar und gibt den aktuellen Wert der atomaren Variable zurück. Entspricht load ( ) .

Es ist veraltet, wenn std:: atomic < T > :: is_always_lock_free den Wert false hat und Überladung (2) an der Überladungsauflösung teilnimmt.

(since C++20)

Parameter

(keine)

Rückgabewert

Der aktuelle Wert der atomaren Variable.
