DEVICE_DSM_OFFLOAD_WRITE_PARAMETERS structure (winioctl.h)

Specifies parameters for the offload write operation. An offload write operation is initiated by specifying DeviceDsmAction_OffloadWrite in the Action member of the DEVICE_MANAGE_DATA_SET_ATTRIBUTES structure passed in a IOCTL_STORAGE_MANAGE_DATA_SET_ATTRIBUTES control code.
