请问能在WDM驱动中使用GetTickCount吗 [复制链接]

如果想获得一个粗劣的计时器，可以用什么方法？

比如 QueryPerfermanceXXXX ?

不能用，以前的帖子中有介绍，函数名字记得不是很清楚了，可以去找找

在驱动中可以使用别的定时器函数。如下:
IoInitializeTimer：
  Associates a timer with the given device object and registers a driver-supplied    IoTimer routine for the device object.
IoStartTimer：
  Enables the timer for a given device object and calls the driver-supplied IoTimer routine once every second.
IoStopTimer ：
  Disables the timer for a given device object so the driver-supplied IoTimer routine is not called unless the driver re-enables the timer.
KeInitializeDpc：
  Initializes a DPC object and sets up a driver-supplied CustomTimerDpc routine that can be called with a given context.
KeInitializeTimer：
  Initializes a notification timer object to the Not-Signaled state.
KeInitializeTimerEx：
  Initializes a notification or synchronization timer object to the Not-Signaled state.
KeSetTimer：
  Sets the absolute or relative interval at which a timer object will be set to the Signaled state; optionally supplies a timer DPC to be executed when the interval expires.
KeSetTimerEx：
  Sets the absolute or relative interval at which a timer object will be set to the Signaled state; optionally supplies a timer DPC to be executed when the interval expires; and optionally supplies a recurring interval for the timer.
KeCancelTimer：
  Cancels a timer object before the interval passed to KeSetTimer expires; dequeues a timer DPC before the timer interval, if any was set, expires.
KeReadStateTimer：
  Returns TRUE if a given timer object is set to the Signaled state.
KeQuerySystemTime ：
  Returns the current system time.
KeQueryTickCount：
  Returns the number of interval-timer interrupts that have occurred since the system was booted.
KeQueryTimeIncrement：
  Returns the number of 100-nanosecond units that are added to the system time at each interval-timer interrupt.
KeQueryInterruptTime：
  Returns the current value of the system interrupt-time count in 100-nanosecond units.
KeQueryPerformanceCounter：
  Returns the system performance counter value in hertz.
