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();
}
