scsi_sense_key(9F)					   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 <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  buf-
       fer.

CONTEXT

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