The SIOC_XSENSE ioctl returns detailed information about device status and errors when such informa-
tion is available. Since there have been multiple versions of the SCSI standard for sense (status) data, mul-
tiple versions of the sense data declaration are provided. The SCSI-1 and non-aligned versions are pro-
vided for backward compatibility only. If no new CHECK-CONDITION-caused REQUEST SENSE com-
mand 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)).
The following information is included from
<sys/scsi.h> :
#define SIOC_XSENSE _IOR(’S’, 7, union sense_data)
/* structure for SIOC_XSENSE ioctl */
typedef union sense_data {
xsense_aligned_t r_sense1a; /* SCSI and CCS devices */
sense_2_aligned_t r_sense2a; /* SCSI-2 devices */
xsense_t r_sense1; /* Do not use; for
* compatibility only
*/
sense_2_t r_sense2; /* Do not use; for
* compatibility only
*/
} sense_data_t;
/*
* Struct xsense_aligned is for examining the sense data of SCSI-1
* and CCS devices.
