奇怪，sfilter 中内容 和 ddk doc内容？

sfilter.c 中 SfCreateCompletion 完成历程：
    if (NULL != event)  {

        KeSetEvent(event, IO_NO_INCREMENT, FALSE);
    }

     if (Irp->PendingReturned) {

        IoMarkIrpPending( Irp );
    }

而在ifs kit 2003文档中：
Using IRP Completion Routines
→→Constraints on Completion Routines下：
Unless the completion routine signals an event, it must check the Irp->PendingReturned flag. If this flag is set, the completion routine must call IoMarkIrpPending to mark the IRP as pending.

If a completion routine signals an event, it should not call IoMarkIrpPending

请高人解惑！

是这样，多谢tooflat!

But:

If a completion routine signals an event, it should not call

如果完成历程 signal event，就不应该call IoMarkIrpPending

怎磨在 CompletionRoutine() 先signal event 后又 IoMarkIrpPending( Irp );

我的理解有问题吗？ :D
