PeriodicTimer rule (ndis)

  • Artikel

The PeriodicTimer rule specifies that the caller of NdisCancelTimerObject must be running at IRQL = PASSIVE_LEVEL if a nonzero value was specified in the MillisecondsPeriod parameter of the NdisSetTimerObject function. If the MillisecondsPeriod parameter of the NdisSetTimerObject function was zero, callers of NdisCancelTimerObject can be running at IRQL <= DISPATCH_LEVEL.

Driver model: NDIS

How to test

At compile time

Run Static Driver Verifier and specify the PeriodicTimer rule.

Use the following steps to run an analysis of your code:
  1. Prepare your code (use role type declarations).
  2. Run Static Driver Verifier.
  3. View and analyze the results.
