This class provides default implementations of non-essential atomic operations for the 32-bit pointer type independent on any specific platform. It also provides prototypes for the atomic operations for the pointer type that have to be implemented separately for each specific platform. These platform-independent and platform-specific atomic operations combined together form a full set of atomic operations for the pointer type.

AtomicTypes | This typedef is an alias to Atomic_TypeTraits<IMP>. |
| Name | Description |
|---|---|
getPtr | Atomically retrieve the value of the specified atomicPtr, providing the sequential consistency memory ordering guarantee. |
getPtrAcquire | Atomically retrieve the value of the specified atomicPtr, providing the acquire memory ordering guarantee. |
getPtrRelaxed | Atomically retrieve the value of the specified atomicPtr, without providing any memory ordering guarantees. |
initPointer | Initialize the specified atomicPtr and set its value to the optionally specified initialValue. |
setPtr | Atomically set the value of the specified atomicPtr to the specified value, providing the sequential consistency memory ordering guarantee. |
setPtrRelaxed | Atomically set the value of the specified atomicPtr to the specified value, without providing any memory ordering guarantees. |
setPtrRelease | Atomically set the value of the specified atomicPtr to the specified value, providing the release memory ordering guarantee. |
swapPtr | Atomically set the value of the specified atomicPtr to the specified swapValue, and return its previous value, providing the sequential consistency memory ordering guarantee. |
swapPtrAcqRel | Atomically set the value of the specified atomicPtr to the specified swapValue, and return its previous value, providing the acquire/release memory ordering guarantee. |
testAndSwapPtr | Conditionally set the value of the specified atomicPtr to the specified swapValue if and only if the value of atomicPtr equals the value of the specified compareValue, and return the initial value of atomicPtr, providing the sequential consistency memory ordering guarantee. The whole operation is performed atomically. |
testAndSwapPtrAcqRel | Conditionally set the value of the specified atomicPtr to the specified swapValue if and only if the value of atomicPtr equals the value of the specified compareValue, and return the initial value of atomicPtr, providing the acquire/release memory ordering guarantee. The whole operation is performed atomically. |
