NAME
     scsi_cname, scsi_dname, scsi_mname, scsi_rname, scsi_sname -
     decode a SCSI name

SYNOPSIS
     #include 



     char *scsi_cname(uchar_t cmd, char **cmdvec);


     char *scsi_dname(int dtype);


     char *scsi_mname(uchar_t msg);


     char *scsi_rname(uchar_t reason);


     char *scsi_sname(uchar_t sense_key);


INTERFACE LEVEL
     Solaris DDI specific (Solaris DDI).

PARAMETERS
     cmd          A SCSI command value.


     cmdvec       Pointer to an array of command strings.


     dtype        Device type.


     msg          A message value.


     reason       A packet reason value.


     sense_key    A SCSI sense key value.


DESCRIPTION
     The scsi_cname() function decodes SCSI commands. cmdvec 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.

Kernel Functions for Drivers                       scsi_cname(9F)



     The scsi_dname() function decodes the peripheral device type
     (for  example,  direct  access  or sequential access) in the
     inquiry data.


     The scsi_mname() function decodes SCSI messages.


     The scsi_rname() function decodes packet completion reasons.


     The scsi_sname() function decodes SCSI sense keys.

RETURN VALUES
     These functions return a pointer to a string. If an argument
     is invalid, they return a string to that effect.

CONTEXT
     These functions can be called from user, interrupt, or  ker-
     nel context.

EXAMPLES
     Example 1 Decoding SCSI tape commands.


     The scsi_cname() function decodes SCSI tape commands as fol-
     lows:


       static char *st_cmds[] = {
                   "\000test unit ready",
                   "\001rewind",
                   "\003request sense",
                   "\010read",
                   "\012write",
                   "\020write file mark",
                   "\021space",
                   "\022inquiry",
                   "\025mode select",
                   "\031erase tape",
                   "\032mode sense",
                   "\033load tape",
                   NULL
           };
           ..
           cmn_err(CE_CONT, "st: cmd=%s", scsi_cname(cmd, st_cmds));
