DESCRIPTION

       The Standard Jukebox Interface (SJI) is a public set of interfaces that
       NetWorker uses to communicate with jukeboxes.  Generally  the  function
       of  this library is to convert SJI commands, as formed by NetWorker, to
       the appropriate SCSI commands (since most autochangers are SCSI based).
       But the underlying attachment to the jukebox is irrelevant to the func-
       tioning of this interface.

       There are three entry points into this library:

       void * sji_open ( char * devname )
              This opens a channel to an SJI compliant jukebox, named devname.
              A  channel  token,  of type void * is returned if the channel is
              opened successfully, otherwise a channel token of type  NULL  is
              returned.  The device name devame can be a specific ordinal SCSI
              address, for example, scsidev@b.t.l, where b is the logical scsi
              bus, t is the SCSI target, and l is the SCSI logical unit number
              (LUN) on that target.  For platforms  that  do  not  use  Legato
              device  drivers, the device name can also be a platform-specific
              style device name, for example, /dev/sjid1u1.

       int sji_cmd ( void *token, int cmd, void *arg )
              This sends an SJI command to the device opened by  the  sji_open
              command.

       void sji_close ( void *token )
              This  closes  a channel to the device opened by the call made to
              the sji_open command.
