Default implementations of non-essential 32-bit unsigned atomic operations.
Declared in <bsls_atomicoperations_default.h>
template<class IMP>
struct AtomicOperations_DefaultUint;This class provides default implementations of non-essential atomic operations for the 32-bit unsigned integer type independent on any specific platform. It also provides prototypes for the atomic operations for the 32-bit unsigned integer type that have to be implemented separately for each specific platform. These platform-independent and platform-specific atomic operations together form a full set of atomic operations for the 32-bit unsigned integer type.
Note that AtomicOperations_DefaultUint is implemented in terms of the following atomic operations on the integer type that must be provided by the IMP template parameter. ` static int getInt(typename AtomicTypes::Int const *atomicInt); static int getIntRelaxed(typename AtomicTypes::Int const *atomicInt); static int getIntAcquire(typename AtomicTypes::Int const *atomicInt); static void setInt(typename AtomicTypes::Int *atomicInt, int value); static void setIntRelaxed(typename AtomicTypes::Int *atomicInt, int value); static void setIntRelease(typename AtomicTypes::Int *atomicInt, int value); static int swapInt(typename AtomicTypes::Int *atomicInt, int swapValue); static int swapIntAcqRel(typename AtomicTypes::Int *atomicInt, int swapValue); static int testAndSwapInt(typename AtomicTypes::Int *atomicInt, int compareValue, int swapValue); static int testAndSwapIntAcqRel(typename AtomicTypes::Int *atomicInt, int compareValue, int swapValue); `
