Kernel Functions for Drivers                   scsi_sense_key(9F)



NAME
     scsi_sense_key, scsi_sense_asc, scsi_sense_ascq  -  retrieve
     fields from SCSI sense data

SYNOPSIS
     #include 



     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);


INTERFACE LEVEL
     Solaris DDI specific (Solaris DDI).

PARAMETERS
     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.


DESCRIPTION
     The scsi_sense_key() function returns the  sense  key  value
     from the sense data contained in the sense_buffer.


     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, regardles 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.

RETURN VALUES
     The scsi_sense_key() function returns the  sense  key  value
     from the sense buffer. The scsi_sense_asc() function returns
     the additional sense code (ASC) from the  sense  buffer  and
     the  scsi_sense_ascq() function returns the additional sense
     code qualifier (ASCQ) from the sense buffer.

CONTEXT
     The      scsi_sense_key(),       scsi_sense_asc(),       and
     scsi_sense_ascq()  functions  can  be  called  from  user or
     interrupt context.
