#include <sys/scsi/scsi.h> uint8_t scsi_sense_key(uint8_t *sense_buffer);
uint8_t scsi_sense_asc(uint8_t *sense_buffer);
uint8_t scsi_sense_ascq(uint8_t *sense_buffer);
Pointer to a buffer containing SCSI sense data. The sense data is expected in wire format starting at the response code. It can be in either fixed or descriptor format.
The scsi_sense_asc() function returns the additional sense code (ASC) value from the sense data contained in the sense_buffer.
The scsi_sense_ascq() function returns the additional sense code qualifier (ASCQ) value from the sense data contained in the sense_buffer.
The scsi_sense_key(), scsi_sense_asc(), and scsi_sense_ascq() functions are used to retrieve values from SCSI sense data, regardless of whether the sense data is in fixed format or descriptor format.
Drivers should use scsi_validate_sense(9F) to ensure that valid sense key, asc, and ascq values are present in the sense data.
