RxScavengeAllFobxs function

RxScavengeAllFobxs scavenges all of the FOBX structures associated with a network mini-redirector device object.

Syntax


VOID RxScavengeAllFobxs(
   PRDBSS_DEVICE_OBJECT RxDeviceObject
);

Parameters

RxDeviceObject

A pointer to the mini-redirector device object for which the scavenge should be done.

Return value

None

Remarks

At cleanup, there are no more user handles associated with the file object. In such cases, the time window between close and cleanup is dictated by the additional references maintained by the memory manager and cache manager. RDBSS uses a scavenger process running on a separate thread to scavenge and purge unneeded FOBX and other structures.

A network mini-redirectors might call RxPurgeAllFobxs and RxScavengeAllFobsx in response to a PnP power change event.

The RxScavengeAllFobxs routine acquires the scavenger mutex, traverses the FobxFinalizationList member on the scavenger object, and inserts any entries found at the tail of the ScavengerFinalizationList member, and then releases the scavenger mutex.

On checked builds, RxScavengeAllFobxs causes the system to ASSERT for the following condition:

  • The NodeTypeCode member of an FOBX structure is not RDBSS_NTC_FOBX.
