Sostituisce atomico il valore puntato dal arg con il risultato di OR bit a bit tra il valore storico di obj e arg, e restituisce il valore obj precedentemente detenuta, come per obj->fetch_and(arg)

Original:

Atomically replaces the value pointed by arg with the result of bitwise OR between the old value of obj and arg, and returns the value obj held previously, as if by obj->fetch_and(arg)
