Detailed Description

Device handle Extended Data. Used for many errors and progress codes to point to the device.

The handle of the device with which the progress or error code is associated. The handle is guaranteed to be accurate only at the time the status code is reported. Handles are dynamic entities between boots, so handles cannot be considered to be valid if the system has reset subsequent to the status code being reported. Handles may be used to determine a wide variety of useful information about the source of the status code.
