Performs a weak atomic compare and exchange operation.

template <class Ty>
inline bool atomic_compare_exchange_strong(
   volatile atomic<Ty> *Atom,
   Ty *Exp,
   Ty Value
) _NOEXCEPT;
template <class Ty>
inline bool atomic_compare_exchange_strong(
   atomic<Ty> *Atom,
   Ty *Exp,
   TyValue
) _NOEXCEPT;

Atom

A pointer to an atomic object that stores a value of type Ty.

Exp

A pointer to a value of type Ty.

Value

A value of type Ty.

A bool that indicates the result of the value comparison.

This method performs a weak atomic compare and exchange operation that has implicit memory_order_seq_cst memory_order arguments. For more information, see atomic_compare_exchange_weak_explicit Function.
