Obtaining Information About a General I/O Target in UMDF

  • Article

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.

The archived UMDF 1 samples can be found in the Windows 11, version 22H2 - May 2022 Driver Samples Update.

For more info, see Getting Started with UMDF.

To obtain information about an I/O target, a UMDF driver can call the following methods that the I/O target object defines:

IWDFIoTarget::GetTargetFile
Returns the framework file object that is associated with the I/O target.

IWDFIoTargetStateManagement::GetState
Returns state information for a local I/O target.

IWDFRemoteTarget::GetState
Returns state information for a remote I/O target.
