IRP請求的完成與返回
irp請求的完成與返回 每當完成了乙個以irp為代表的i o操作請求的時候，就要執行irp的善後操作iocompleterequest 這是個巨集操作，定義為函式iofcompleterequest define iocompleterequest iofcompleterequest 如前所述，以...
Windows驅動開發 IRP的完成例程
windows驅動開發技術詳解 331頁，在將irp傳送給底層驅動或其他驅動之前，可以對irp設定乙個完成例程，一旦底層驅動將irp完成後，irp完成例程立刻被處罰，通過設定完成例程可以方便地使程式設計師了解其他驅動對irp進行的處理，不管是呼叫自己的底層驅動或是呼叫其他驅動，都是使用核心函式ioc...
