NAME

std::atomic_ref::fetch_xor - std::atomic_ref::fetch_xor

Synopsis

T fetch_xor( T arg, (since C++20)
std::memory_order order = (member only of atomic_ref<Integral>
std::memory_order_seq_cst ) const noexcept; template specialization)

Atomically replaces the current value of the referenced object with the result of
bitwise XOR of the value and arg. This operation is a 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 of the referenced object, immediately preceding the effects of this
function.
