hpcx82 / singleton.cpp

Created July 1, 2012 09:31

Spin lock implementation in Windows and depends on it a double-checked singleton.

	// we use double-lock check in singleton to solve the problem we met in spinlock1.cpp, but hey, that itself is a lock, it has to use some atomic intrusion/memory barrier to solve this synchronization problem

	template<class T>
	class SingletonHolder
	{
	private:
	static volatile T* instance;
	static volatile int m_lockObj;
	SingletonHolder() {}
