BloombergLP::bsls::AtomicOperations_DefaultInt

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.
