T fetch_and( T arg,
std::memory_order order = std::memory_order_seq_cst ) const noexcept;
| (since C++20) (member only of atomic_ref<Integral> template specialization) |
Atomically replaces the current value of the referenced object with the result of bitwise AND of the value and arg. This operation is a read-modify-write operation. Memory is affected according to the value of order.
| arg | - | the other argument of bitwise AND |
| order | - | memory order constraints to enforce |
The value of the referenced object, immediately preceding the effects of this function.
