Description

AtomicOperations_DefaultInt<IMP>

This class provides default implementations of non‐essential atomic operations for the 32‐bit integer type independent on any specific platform. It also provides prototypes for the atomic operations for the 32‐bit 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 integer type.

AtomicOperations_DefaultInt64<IMP>

This class provides default implementations of non‐essential atomic operations for the 64‐bit integer type independent on any specific platform. It also provides prototypes for the atomic operations for the 64‐bit 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 64‐bit integer type.

AtomicOperations_DefaultUint<IMP>

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.

AtomicOperations_DefaultUint64<IMP>

This class provides default implementations of non‐essential atomic operations for the 64‐bit unsigned integer type independent on any specific platform. It also provides prototypes for the atomic operations for the 64‐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 64‐bit unsigned integer type.

AtomicOperations_DefaultPointer32<IMP>

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.
