View the official Windows Driver Kit DDI referenceNo description available.
The ExReleaseRundownProtection routine releases run-down protection that the caller previously acquired by calling the ExAcquireRundownProtection routine.
RunRef [in, out]A pointer to an EX_RUNDOWN_REF structure that was initialized by a previous call to the ExInitializeRundownProtection routine. The run-down protection routines use this structure to track the run-down status of the associated shared object. This structure is opaque to drivers.
A driver that calls ExAcquireRundownProtection to acquire run-time protection for an object access is responsible for calling ExReleaseRundownProtection to release the run-time protection when the access is finished.
As long as the run-down block itself is nonpaged, this function can be called at DISPATCH_LEVEL.
