std::atomic<T>::fetch_and

Since C++11

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

# Declarations

member only of atomic<Integral > specializations

T fetch_and( T arg, std::memory_order order =
std::memory_order_seq_cst ) noexcept;

(since C++11)

T fetch_and( T arg, std::memory_order order =
std::memory_order_seq_cst ) volatile noexcept;

(since C++11)

# Parameters

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

# Return value

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