[in] A pointer to a string that identifies the device interface instance. This string was obtained from a previous call to the IoGetDeviceInterfaces, IoGetDeviceInterfaceAlias, or IoRegisterDeviceInterface routine. PropertyKey [in] A pointer to a DEVPROPKEY structure that contains the device interface property key. Lcid [in] Specifies a locale

Subject: [ntdev] IoRegisterDeviceInterface Hi all. I am in a self-project in which I try to port my WINNT driver architecture in WDM architecture. Several issues have arisen during this attempt. One of those, maybe the most simple, is usage of "IoRegisterDeviceInterface" function. How can I figure out what is the symbolic name of the successful 10/01/2018 IoRegisterDeviceInterface.

Once a driver registers itself with the HID class driver, IoRegisterDeviceInterface doesn't work. Also, sending special ioctl's to the HID driver itself doesn't work, because it discards IOCTL's it isn't expecting. So, there are two methods that are suggested. If your device only expects reads, send a write request to the HID driver.

I am trying to simulate a dynamic mount request, iss The driver then calls IoSetDeviceInterfaceState to enable the interface using the symbolic link name returned by IoRegisterDeviceInterface.

IoRegisterDeviceInterface. by Brian D. Star » Sat, 02 Nov 2002 04:40:13 . Hello, I am developing a WDM driver for a series of PCI boards that record and playback specific data types. Under NT the application would open a handle to the first board and then send a control call to it to find out how many boards were physically attached, I then knew the symbolic names The official Windows Driver Kit DDI reference documentation sources - MicrosoftDocs/windows-driver-docs-ddi returned by IoRegisterDeviceInterface. You need that to enable and disable interface state. Technically there is nothing wrong in calling IoRegisterDeviceInterface because the registration happens on the PDO and the symbolic link to the PDO isn't created until you enable it later in the Start-device. By creating after IoCreateDevice, it makes it easier to store Avant cette version, il appelait IoRegisterDeviceInterface avec GUID_DEVINTERFACE_HID et le pointeur ReferenceString défini sur 0.

How can I figure out what is the symbolic name of the successful IoRegisterDeviceInterface() call within HwFindAdapter() routine in my storport miniport driver fails. The stack trace for the HwFindAdapter shows that IoAttachDeviceToStack function is being called. Do we still need to call the IoRegisterDeviceInterface() call inside the HwFindAdapter routine ? Thanks, Please see stack trace below [in] A pointer to a string that identifies the device interface instance.

Distinguishing a FDO request from a PDO request. One of the first big issues that the bus driver writer must address is the creation and management of two different types of device objects. This chapter from Windows Internals, Part 2, 6th Edition lists the design goals of the Windows I/O system which have influenced its implementation. It covers the components that make up the I/O system, including the I/O manager, Plug and Play (PnP) manager, and power manager, and also examines the structure and components of the I/O system and the various types of device drivers.

IoRegisterDeviceInterface function (wdm.h) 04/30/2018; 3 minutes to read; In this article. The IoRegisterDeviceInterface routine registers a device interface class, if it has not been previously registered, and creates a new instance of the interface class, which a driver can subsequently enable for use by applications or other system components.

A kernel-mode component typically calls this routine to get a list of all enabled device interface instances of a particular device interface class. Subject: [ntdev] IoRegisterDeviceInterface Hi all.
