.SH DESCRIPTION
.sp
.LP
The \fBscsi_cname()\fR function decodes \fBSCSI\fR commands. \fIcmdvec\fR is a
pointer to an array of strings. The first byte of the string is the command
value, and the remainder is the name of the command.
.sp
.LP
The \fBscsi_dname()\fR function decodes the peripheral device type (for
example, direct access or sequential access) in the inquiry data.
.sp
.LP
The \fBscsi_mname()\fR function decodes \fBSCSI \fRmessages.
.sp
.LP
The \fBscsi_rname()\fR function decodes packet completion reasons.
.sp
.LP
The \fBscsi_sname()\fR function decodes \fBSCSI\fR sense keys.
.SH RETURN VALUES
.sp
.LP
These functions return a pointer to a string. If an argument is invalid, they
return a string to that effect.
.SH CONTEXT
.sp
.LP
These functions can be called from user, interrupt, or kernel context.
.SH EXAMPLES
.LP
\fBExample 1 \fRDecoding SCSI tape commands.
.sp
.LP
The \fBscsi_cname()\fR function decodes \fBSCSI \fRtape commands as follows:
