ExReleaseRundownProtection function

The ExReleaseRundownProtection routine releases run-down protection that the caller previously acquired by calling the ExAcquireRundownProtection routine.

Syntax

void ExReleaseRundownProtection(
  PEX_RUNDOWN_REF RunRef
);

Parameters

RunRef

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.
