baiyanhuang / 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>

{
private:
static volatile T* instance;
static volatile int m_lockObj;
