I uses boost::atomic to make it usable without c++0x http://www.chaoticmind.net/~hcb/projects/boost.atomic/

#include <boost/atomic.hpp>

class AtomicPointer { private: boost::atomic<void> rep_; public: AtomicPointer() { } explicit AtomicPointer(void v) { } inline void* Acquire_Load() const { return rep_.load(boost::memory_order_acquire); } inline void Release_Store(void* v) { rep_.store(v, boost::memory_order_release); } inline void* NoBarrier_Load() const { return rep_.load(boost::memory_order_relaxed); } inline void NoBarrier_Store(void* v) { rep_.store(v, boost::memory_order_relaxed); } };
