如果有效的處理器型別是 AMD64,我會尋求 KERNELBASE!SleepEx + 0xab 函式。如果所有符號會正確地都解析,此函式應該框架 1 中: c++ 0:000> knL2 # Child-SP RetAddr Call Site0000000000'001cfc08000007fe'fd9b1203 ntdll!NtDelayExecution+0xa 01 00000000'001cfc100000000...
SleepEx+0xab However, based on the level of symbol resolution available, the function symbol I’m looking for may or may not be in the expected frame. If you open the test01 x86 dump file and don’t specify a symbol path, you can see an example of this. The KERNELBASE!Sleep call ...
Applications that simply need to enter an alertable wait state without waiting for any event objects to be signaled should use the WindowsSleepExfunction. Example Code The following example demonstrates the use of theWSAWaitForMultipleEventsfunction. ...
SleepEx WaitForSingleObjectEx WaitForMultipleObjectsEx SignalObjectAndWait MsgWaitForMultipleObjectsEx当线程进入可警报状态时,会发生以下事件:内核检查线程的 APC 队列。 如果队列包含回调函数指针,则内核会从队列中删除指针并将其发送到线程。 线程执行回调函数。 对于队列中剩余的每个指针重复步骤 1 和 2。 当队列为...
应用程序使用WaitForSingleObjectEx、WaitForMultipleObjectsEx、MsgWaitForMultipleObjectsEx、SignalObjectAndWait和SleepEx函数进入可警报的等待状态。 有关可发出警报的等待状态和重叠 I/O 操作的详细信息,请参阅关于同步。 如果直接写入具有已装载文件系统的卷,则必须先获取该卷的独占访问权限。 否则,可能会导致数据损坏或系...

Sleep SleepEx Any of these calls simply mean that the thread making this call wants to step aside and wait for some event to occur before it continues with its work. Windows NT will "wake up" the thread when it can continue processing. ...

服务器进程可以使用任何等待函数或SleepEx来确定何时发出事件对象的状态信号,然后它可以使用HasOverlappedIoCompleted宏来确定ConnectNamedPipe操作何时完成。 如果指定的管道句柄处于非阻止模式,则 ConnectNamedPipe始终会立即返回。 在非阻止模式下,ConnectNamedPipe在首次为与以前的客户端断开连接的管道实例调用它时返...
