Default implementations of non‐essential 32‐bit integer atomic operations.

Synopsis

Declared in <bsls_atomicoperations_default.h>

template<class IMP>
struct AtomicOperations_DefaultInt;

Description

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.
