BOOLGetThreadTimes( [in] HANDLE hThread, [out] LPFILETIME lpCreationTime, [out] LPFILETIME lpExitTime, [out] LPFILETIME lpKernelTime, [out] LPFILETIME lpUserTime ); 参数 [in] hThread 要获取其计时信息的线程的句柄。 句柄必须具有THREAD_QUERY_INFORMATION或THREAD_QUERY_LIMITED_INFORMATION访问...
昨天我在一篇博文中 《对老赵写的简单性能计数器的修改》 提到用 GetThreadTimes 这个Win32 API 来获取线程实际运行时间。今天我又深入研究了一下,发现这个API 返回的时间并不准确。 首先我们先看一下 GetThreadTimes 的实现原理: 在kernel32.dll 内部 GetThreadTimes 首先调用NtQueryInformationThread获取线程TCB信息,然后...
BOOL GetThreadTimes ( HANDLE hThread, LPFILETIME lpCreationTime, LPFILETIME lpExitTime, LPFILETIME lpKernelTime, LPFILETIME lpUserTime ); Parameters hThread [in] Open handle that specifies the thread whose timing information is sought.
