The DEVICE_DSM_OFFLOAD_READ_PARAMETERS structure specifies the parameters for an offload read action related to the data-set attributes for a device.
FlagsNot used. Set to 0.
TimeToLiveThe duration, in milliseconds, for which the requested data ranges should remain valid.
ReservedReserved.
This structure is used in an offload read action for an IOCTL_STORAGE_MANAGE_DATA_SET_ATTRIBUTES request. The Action member of the DEVICE_DSM_INPUT structure is set to DeviceDsmAction_OffloadRead.
The ParameterBlockOffset and ParameterBlockLength members of DEVICE_DSM_INPUT structure are set to the location and length of the DEVICE_DSM_OFFLOAD_READ_PARAMETERS structure in the input 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 read.
See DEVICE_DSM_ACTION Descriptions for more details about this action.
