Defined in header <stdatomic.h>
C atomic_fetch_or( volatile A* obj, M arg );
(1)
C atomic_fetch_or_explicity( volatile A* obj, M arg, memory_order order );
(2)
Sostituisce atomico il valore puntato dal obj con il risultato di OR bit a bit tra il valore storico di obj e arg, e restituisce il valore obj precedentemente detenuta. L'operazione è lettura-modifica-scrittura. La prima memoria versione ordini accessi secondo memory_order_seq_cst, la seconda memoria versione ordini accessi secondo order.
Original:
Atomically replaces the value pointed by obj with the result of bitwise OR between the old value of obj and arg, and returns the value obj held previously. The operation is read-modify-write operation. The first version orders memory accesses according to memory_order_seq_cst, the second version orders memory accesses according to order.

Questo è un funzione generica definita per ogni tipologia di oggetto atomici. A è il tipo di un oggetto atomico, M può essere il non-atomica tipo corrispondente al A se A è atomico tipo intero, o se ptrdiff_t A è di tipo puntatore atomica.
Original:
This is a funzione generica defined for all atomic object types. A is the type of an atomic object, M is either the non-atomic type corresponding to A if A is atomic integer type, or ptrdiff_t if A is atomic pointer type.
