The SIOC_XSENSE ioctl returns detailed information about device status and errors when such infor-
mation is available. Since there have been multiple versions of the SCSI standard for sense (status) data,
multiple versions of the sense data declaration are provided. The SCSI-1 and non-aligned versions are
provided for backward compatibility only. If no new CHECK-CONDITION-caused REQUEST SENSE
command data has been obtained since the last SIOC_XSENSE ioctl call, the
xsense_aligned.error_class and sense_2_aligned.error_code fields will contain the
value zero. Applications which require more accurate REQUEST SENSE data handling should use the
SCSI device-control driver (see scsi_ctl (7)).
