atomic_fetch_xor Function
Performs a bitwise exclusive or on a value and an existing value that is stored in an atomic object.
template <class T>
inline T atomic_fetch_xor(
volatile atomic<T>* Atom,
T Value); noexcept
template <class T>
inline T atomic_fetch_xor(
volatile atomic<T>* Atom,
T Value); noexcept
Parameters
Atom
A pointer to an atomic object that stores a value of type T.Value
A value of type T.
Return Value
The value contained by the atomic object immediately before the operation was performed.
Remarks
The atomic_fetch_xor function performs a read-modify-write operation to replace the stored value of Atom with a bitwise exclusive or of Value and the current value that is stored in Atom, using the memory_order_seq_cstmemory_order.
