View the official Windows Driver Kit DDI referenceNo description available.
The IO_DEVICE_HINT_ECP_CONTEXT structure contains the extra create parameters (ECP) context that the I/O manager uses to pass back information to the filter manager about a reparse when the reparse target goes to a new device.
TargetDeviceThe reparse target device.
RemainingNameString containing the remaining portion of the pathname string.
The system-defined GUID_ECP_IO_DEVICE_HINT value is used with this ECP context structure when calling ECP-related support routines such as FltAllocateExtraCreateParameter and FsRtlRemoveExtraCreateParameter.
See Introduction to extra create parameters for more information.
