An AVStream minidriver's AVStrMiniRemoveEvent routine is called when a client requests to be removed from the notification queue for an event. This routine is optional.
FileObject [in]Pointer to the file object for which to remove the event.
EventEntry [in]Pointer to an AVStream-generated KSEVENT_ENTRY structure.
The minidriver specifies this routine's address in the RemoveHandler member of a KSEVENT_ITEM structure. Event Handling in AVStream describes how the minidriver provides this structure to the class driver.
If the minidriver provides AVStrMiniRemoveEvent and either does not specify an AddHandler or specifies an AddHandler that calls KsXxxAddEvent, then the minidriver's AVStrMiniRemoveEvent must call RemoveEntryList with a pointer to the LIST_ENTRY structure in the KSEVENT_ENTRY structure:
&EventEntry -> ListEntry
Otherwise, your AVStrMiniRemoveEvent should reverse the steps taken in the AddHandler.
