La libreria atomica fornisce componenti per le operazioni atomiche a grana fine che consentono lockless programmazione concorrente. Ogni operazione atomica è indivisibile per quanto riguarda qualsiasi altra operazione atomica che coinvolge lo stesso oggetto. Oggetti atomici sono l'unica C + + gli oggetti liberi di razze dati; che, se un thread scrive in un atomico mentre un altro thread legge da esso, il comportamento è ben definito.

Original:

The atomic library provides components for fine-grained atomic operations allowing for lockless concurrent programming. Each atomic operation is indivisible with regards to any other atomic operation that involves the same object. Atomic objects are the only C++ objects free of data races; that is, if one thread writes to an atomic while another thread reads from it, the behavior is well-defined.
