Setting and Clearing Timers
After allocating and initializing a timer with the NdisAllocateTimerObject function, an NDIS 6.0 driver calls the NdisSetTimerObject function to set a timer object to fire after a specified interval or periodically.
The DueTime parameter of NdisSetTimerObject specifies the interval to elapse before a timer fires and NDIS calls the associated NetTimerCallback function. The expiration time is expressed in system time units (100-nanosecond intervals).
If the MillisecondsPeriod parameter of NdisSetTimerObject is not zero, the timer fires periodically and MillisecondsPeriod specifies the periodic time interval, in milliseconds, that elapses between each time a periodic timer fires and the next call to the NetTimerCallback function.
Your driver can call the NdisCancelTimerObject function to cancel a timer that is associated with a previous call to the NdisSetTimerObject function. NDIS might still call NetTimerCallback if the timeout has already expired before the call to NdisCancelTimerObject.
