Reserved.
The offset, in bytes, within the data block specified by Token to begin writing from.
The unique identifier of the data block to write from.
This structure is used in an offload write action for an IOCTL_STORAGE_MANAGE_DATA_SET_ATTRIBUTES request. The Action member of the DEVICE_DSM_INPUT structure is set to DeviceDsmAction_OffloadWrite.
The ParameterBlockOffset and ParameterBlockLength members of DEVICE_DSM_INPUT are set to the location and length of the DEVICE_DSM_OFFLOAD_WRITE_PARAMETERS structure in the system buffer of the IOCTL_STORAGE_MANAGE_DATA_SET_ATTRIBUTES request.
The DataSetRangesOffset and DataSetRangesLength members of DEVICE_DSM_INPUT specify the DEVICE_DSM_RANGE structures for the extents of the offload write.
See DEVICE_DSM_ACTION Descriptions for more details about this action.
