windows临界区锁的封装与实现

基于临界区锁类的定义(.h)：

1 class CMyLock
{
public:
    CMyLock();
    ~CMyLock();
public:
    void Lock();
    void Unlock();

private:
    CRITICAL_SECTION m_cs;
    
};
2 实现方法(.cpp)

CMyLock::CMyLock()
{
    InitializeCriticalSection(&m_cs);
}

CMyLock::~CMyLock()
{
    DeleteCriticalSection(&m_cs);
}

void CMyLock::Lock()
{
    EnterCriticalSection(&m_cs);
}

void CMyLock::Unlock()
{
    LeaveCriticalSection(&m_cs);
}

3 自动锁

class CAutoLock{
public:
    CAutoLock(CMyLock* pMyLock);
    ~CAutoLock();
public:
    CMyLock* m_pMyLock;
};

CAutoLock::CAutoLock(CMyLock* pMyLock)
{
    m_pMyLock = pMyLock;
    if (m_pMyLock)
        m_pMyLock->Lock();

}

CAutoLock::~CAutoLock()
{
    if (m_pMyLock)
        m_pMyLock->Unlock();
}
