WDF_IO_QUEUE_CONFIG 結構是做為WdfIoQueueCreate的輸入參數。 從KMDF 1.9 版開始,驅動程式可以使用NumberOfPresentedRequests成員來指定架構異步傳遞至平行 I/O 佇列要求處理程式的最大 I/O 要求數目。 架構將指定的 I/O 要求數目傳遞給驅動程式之後,在驅動程式完成、取消或重新佇列至少一個要求之前,它不會...

指定I/O 队列的WDF_IO_QUEUE_CONFIG结构的DispatchType成员不是WdfIoQueueDispatchManual。 驱动程序以前调用了WdfIoQueueReadyNotify并注册了EvtIoQueueState回调函数。 驱动程序正在尝试取消注册其通知回调函数,但未注册回调函数,或者驱动程序尚未调用WdfIoQueueStop或WdfIoQueueStopSynchronously。
