WDF_IO_QUEUE_DISPATCH_TYPE 列挙型

The WDF_IO_QUEUE_DISPATCH_TYPE enumeration type identifies the request dispatching methods that can be associated with a framework queue object.

構文

typedef enum _WDF_IO_QUEUE_DISPATCH_TYPE {
  WdfIoQueueDispatchInvalid      = 0,
  WdfIoQueueDispatchSequential   = 1,
  WdfIoQueueDispatchParallel     = 2,
  WdfIoQueueDispatchManual       = 3,
  WdfIoQueueDispatchMax          = 4 
} WDF_IO_QUEUE_DISPATCH_TYPE;

定数

WdfIoQueueDispatchInvalid

Reserved for internal use.

WdfIoQueueDispatchSequential

The I/O queue's requests are presented to the driver's request handlers one at a time. The framework does not deliver the next request until a driver has called WdfRequestComplete to complete the current request.

WdfIoQueueDispatchParallel

The framework presents requests to the driver's request handlers as soon as the requests are available.

WdfIoQueueDispatchManual

The framework places requests into the queue but does not deliver them to the driver. The driver must retrieve requests from the queue by calling WdfIoQueueRetrieveNextRequest.

WdfIoQueueDispatchMax

Reserved for internal use only.

解説

For more information, see Dispatching Methods for I/O Requests.
