IrqlKeWaitForMultipleObjects rule (wdm)

The IrqlKeWaitForMultipleObjects rule specifies that callers of the KeWaitForMultipleObjects routine must be running at proper IRQL based upon the Timeout parameter.

Callers of IrqlKeWaitForMultipleObjects routine can be running at IRQL <= DISPATCH_LEVEL, except in the following situations:

• If Timeout <> 0, the caller of the KeWaitForMultipleObjects routine must be running at IRQL <= APC_LEVEL.

• If Timeout != NULL and *Timeout = 0, the caller of the KeWaitForMultipleObjects routine must be running at IRQL = DISPATCH_LEVEL.

• If Timeout = NULL, or *Timeout != 0, the caller of the KeWaitForMultipleObjects routine must running at IRQL <= APC_LEVEL.

Driver model: WDM

How to test

At compile time
Run Static Driver Verifier and specify the IrqlKeWaitForMultipleObjects rule. Use the following steps to run an analysis of your code: Prepare your code (use role type declarations). Run Static Driver Verifier. View and analyze the results. For more information, see Using Static Driver Verifier to Find Defects in Drivers.
