| 释义 | DeleteCriticalSection 语法： C++ void WINAPI DeleteCriticalSection( __inout LPCRITICAL_SECTION lpCriticalSection ); DeleteCriticalSection函数 释放由一个无主的临界区对象使用的资源。 参数 lpCriticalSection [ in , out ] 一个临界区对象的指针。该对象必须早先已被初始化InitializeCriticalSection功能。 返回值 这个函数没有返回值。 备注 删除临界区对象释放所有系统由对象使用的资源。 经过一个临界区对象已被删除，不引用任何功能上(如加锁，TryEnterCriticalSection，和LeaveCriticalSection)比InitializeCriticalSection和InitializeCriticalSectionAndSpinCount其他重要路段经营对象。如果您尝试这样做，内存损坏和其他可能发生意外错误。 如果一个关键部分删除，而它仍然拥有的对删除的关键部分所有权等待线程的状态是不确定的。 实例 举一个例子，它使用DeleteCriticalSection，请参阅使用临界区对象。 要求： 最低支持：client－Windows 2000专业版 最低支持server－Windows 2000服务器 HeaderWinbase.h(头文件：winuser.h) LibraryKernel32.lib DLLKernel32.dll 参见 临界区对象 加锁 InitializeCriticalSection LeaveCriticalSection 同步功能 TryEnterCriticalSection 如果有任何问题和意见，请发送给微软(wsddocfb@microsoft.com) 生成日期：2009年8月27日 ＝＝英文原文＝＝DeleteCriticalSection Function Releases all resources used by an unowned critical section object. Syntax C++ void WINAPI DeleteCriticalSection( __inout LPCRITICAL_SECTION lpCriticalSection ); Parameters lpCriticalSection [in, out] A pointer to the critical section object. The object must have been previously initialized with the InitializeCriticalSection function. Return Value This function does not return a value. Remarks Deleting a critical section object releases all system resources used by the object. After a critical section object has been deleted, do not reference the object in any function that operates on critical sections (such as EnterCriticalSection , TryEnterCriticalSection , and LeaveCriticalSection ) other than InitializeCriticalSection and InitializeCriticalSectionAndSpinCount . If you attempt to do so, memory corruption and other unexpected errors can occur. If a critical section is deleted while it is still owned, the state of the threads waiting for ownership of the deleted critical section is undefined.
