 SCSI_SENSE_KEY 9F "Jun 28, 2006"
 NAME
scsi_sense_key, scsi_sense_asc, scsi_sense_ascq - retrieve fields from SCSI
sense data
 SYNOPSIS

#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);


 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.
