ExReleaseRundownProtection routine
The ExReleaseRundownProtection routine releases run-down protection that the caller previously acquired by calling the ExAcquireRundownProtection routine.
Syntax
VOID ExReleaseRundownProtection( _Inout_ PEX_RUNDOWN_REF RunRef );
Parameters
- 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.
Return value
None.
Remarks
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.
