CSingleLock::CSingleLock

构造 CSingleLock 对象。

explicit CSingleLock( 
   CSyncObject* pObject, 
   BOOL bInitialLock = FALSE  
);

参数

  • pObject
    指向同步过程将捕获的对象。 不能为 NULL

  • bInitialLock
    指定是否首次尝试访问已提供的对象。

备注

此功能通常从组件个受控资源的内部访问成员函数。

示例

// m_CritSection is a data member (of type CCriticalSection)
// of an existing class that implements the resource being shared.

// Relate the synchronization object (m_CritSection) with
// our CSingleLock object. 
CSingleLock singleLock(&m_CritSection);
singleLock.Lock();  // Attempt to lock the shared resource
if (singleLock.IsLocked())  // Resource has been locked
{
   //...use the shared resource...

   // Now that we are finished, 
   // unlock the resource for others.
   singleLock.Unlock();
}
