定义部分：

// CThCriticalSectionObj

class CThCriticalSectionObj
{
public:
CThCriticalSectionObj();
~CThCriticalSectionObj();

void Acquire();
void Release();

private:
CThCriticalSectionObj(const CThCriticalSectionObj &);
CThCriticalSectionObj & operator = (const CThCriticalSectionObj &);

private:
#ifdef WIN32
CRITICAL_SECTION m_obj;
#else
pthread_mutex_t m_obj;
#endif
};

实现部分：

//////////////////////////////////////////////////////////////////////////
// CThCriticalSectionObj
