RTL_CRITICAL_SECTION_DEBUG 结构 前面我们注意到,在 RTL_CRITICAL_SECTION 结构内,DebugInfo 字段指向一个 RTL_CRITICAL_SECTION_DEBUG 结构,该结构给出如下: struct _RTL_CRITICAL_SECTION_DEBUG { WORD Type; WORD CreatorBackTraceIndex; RTL_CRITICAL_SECTION *CriticalSection; LIST_ENTRY ProcessLocksList; DWORD ...
关键区机制主要是通过下面这样的RTL_CRITICAL_SECTION结构来实现的,可以通过dt命令查看该结构定义: 0:002>dtRTL_CRITICAL_SECTIONTest1!RTL_CRITICAL_SECTION+0x000DebugInfo :Ptr32_RTL_CRITICAL_SECTION_DEBUG+0x004LockCount :Int4B+0x008RecursionCount :Int4B+0x00cOwningThread :Ptr32Void+0x010LockSemaphore :Ptr...
DeleteCriticalSection(它将发出一个调用该事件的 CloseHandle 调用,并在必要时释放该调试结构),否则将会发生资源泄漏。 SpinCount仅用于多处理器系统。MSDN 文档对此字段进行如下说明:“在多处理器系统中,如果该临界区不可用,调用线程将在对与该临界区相关的信号执行等待操作之前,旋转 dwSpinCount ...

void EnterCriticalSection( LPCRITICAL_SECTION lpCriticalSection ); Parameters lpCriticalSection [in] Pointer to the critical section object. Return Value None. Remarks The threads of a single process can use a critical section object for mutual-exclusion synchronization. The process is responsible for...
synchronization. The process is responsible for allocating the memory used by a critical section object, which it can do by declaring a variable of typeCRITICAL_SECTION. Before using a critical section, some thread of the process must call theInitializeCriticalSectionfunction to initialize the object...

If a thread terminates while it has ownership of a critical section, the state of the critical section is undefined. 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. ...
