The sense data is expected in wire format starting at the response code. It can be in either fixed or descriptor format. .RE .SH DESCRIPTION .sp .LP The \fBscsi_sense_key()\fR function returns the sense key value from the sense data contained in the sense_buffer. .sp .LP The \fBscsi_sense_asc()\fR function returns the additional sense code (\fBASC\fR) value from the sense data contained in the sense_buffer. .sp .LP The \fBscsi_sense_ascq()\fR function returns the additional sense code qualifier (\fBASCQ\fR) value from the sense data contained in the sense_buffer. .sp .LP The \fBscsi_sense_key()\fR, \fBscsi_sense_asc()\fR, and \fBscsi_sense_ascq()\fR functions are used to retrieve values from \fBSCSI\fR sense data, regardless of whether the sense data is in fixed format or descriptor format. .sp .LP Drivers should use \fBscsi_validate_sense\fR(9F) to ensure that valid sense key, \fBasc\fR, and \fBascq\fR values are present in the sense data. .SH RETURN VALUES .sp .LP The \fBscsi_sense_key()\fR function returns the sense key value from the sense buffer. The \fBscsi_sense_asc()\fR function returns the additional sense code (\fBASC\fR) from the sense buffer and the \fBscsi_sense_ascq()\fR function returns the additional sense code qualifier (\fBASCQ\fR) from the sense buffer. .SH CONTEXT .sp .LP The \fBscsi_sense_key()\fR, \fBscsi_sense_asc()\fR, and \fBscsi_sense_ascq()\fR functions can be called from user or interrupt context. .SH SEE ALSO .sp .LP \fBscsi_ext_sense_fields\fR(9F), \fBscsi_find_sense_descr\fR(9F), \fBscsi_sense_cmdspecific_uint64\fR(9F), \fBscsi_sense_info_uint64\fR(9F), \fBscsi_validate_sense\fR(9F)
