IWDFFile interface

[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.]

The IWDFFile interface exposes the file object that represents the HANDLE that is returned by the Microsoft Win32 CreateFile function. All further operations on this handle, such as calls to the Win32 ReadFile function and the DeviceIoControl function, are sent to this file object.


The IWDFFile interface has these methods.

Method Description
IWDFFile::GetDevice The GetDevice method returns the interface to the device object that a file object is associated with.
IWDFFile::RetrieveFileName The RetrieveFileName method retrieves the full name of the file that is associated with the underlying kernel-mode device.


End of support Unavailable in UMDF 2.0 and later.
