IQueueCallbackDeviceIoControl interface

-description

[Warning: UMDF 2 is the latest version of UMDF and supersedes UMDF 1. All new UMDF drivers should be written using UMDF 2. No new features are being added to UMDF 1 and there is limited support for UMDF 1 on newer versions of Windows 10. Universal Windows drivers must use UMDF 2. For more info, see Getting Started with UMDF.]

An I/O queue object notifies a driver when a device I/O control request is available for the driver. The I/O queue object notifies the driver in response to an application calling the Microsoft Win32 DeviceIoControl function. The driver can handle the notification by registering the IQueueCallbackDeviceIoControl interface.

-inheritance

The IQueueCallbackDeviceIoControl interface inherits from the IUnknown interface. IQueueCallbackDeviceIoControl also has these types of members:

  • Methods

-remarks

A driver registers the IQueueCallbackDeviceIoControl interface when it calls the IWDFDevice::CreateIoQueue method to create an I/O queue or to configure the default I/O queue. For more information about creating or configuring an I/O queue, see Configuring Dispatch Mode for an I/O Queue.
