VOID FLTAPI FltUnregisterFilter(
  PFLT_FILTER Filter
);

Parameters

Filter

Opaque filter pointer returned by FltRegisterFilter.

Return value

None

Remarks

FltUnregisterFilter unregisters the minifilter driver's callback routines and removes any contexts that the minifilter driver has set on files, volumes, instances, streams, or stream handles. It also calls the minifilter driver's InstanceTeardownStartCallback and InstanceTeardownCompleteCallback (PFLT_INSTANCE_TEARDOWN_CALLBACK) routines for each minifilter driver instance.

A minifilter driver typically calls FltUnregisterFilter from its unload routine when it is about to be unloaded.

A minifilter driver can only call FltUnregisterFilter to unregister itself, not another minifilter driver.

To register a minifilter driver, call FltRegisterFilter.
