      Atomically replaces the current value with the result of bitwise AND of the value andarg. The operation is read-modify-write operation. Memory is affected according to the value oforder.

      It is deprecated ifstd::atomic<T>::is_always_lock_free isfalse and overload(2) participates in overload resolution.

      (since C++20)

      [edit]Parameters

      arg - the other argument of bitwise AND
      order - memory order constraints to enforce

      [edit]Return value

      The value immediately preceding the effects of this function in themodification order of*this.

      [edit]See also

      replaces the atomic object with the result of bitwise AND with a non-atomic argument and obtains the previous value of the atomic
