Remplace atomiquement la valeur pointée par arg avec le résultat d'un OU binaire entre l'ancienne valeur de obj et arg, et renvoie la valeur obj déjà jugé, comme si par 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)
