std::atomic<T>::fetch_xor: std::atomic<T>::fetch_xor

NAME

std::atomic<T>::fetch_xor - std::atomic<T>::fetch_xor

Synopsis


T fetch_xor( T arg,
std::memory_order order = std::memory_order_seq_cst ) noexcept; (since C++11)
T fetch_xor( T arg, (member only of atomic<Integral> template specialization)
std::memory_order order = std::memory_order_seq_cst ) volatile noexcept;


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

Parameters


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

Return value


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