Atomicamente substitui o valor apontado por arg com o resultado do OR bit a bit entre o valor antigo de obj e arg, e retorna o valor obj realizada anteriormente, como por 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)
