   3 NAME
   4        zcons - Zone console device driver
   5 
   6 DESCRIPTION
   7        The zcons character driver exports the console for system zones. The
   8        driver is comprised of two "sides:" a master side with which
   9        applications in the global zone communicate, and a slave side, which
  10        receives I/O from the master side. The slave side is available in the
  11        global zones.
  12 


  13 
  14        Applications must not depend on the location of /dev or /devices
  15        entries exported by zcons. Inside a zone, the zcons slave  side is
  16        fronted by /dev/console and other console-related  symbolic links,
  17        which are used by applications that expect to write to the system
  18        console.

  20 
  21        The zcons driver is Sun Private, and may change in future releases.

   3 NAME
   4      zcons - Zone console device driver
   5 
   6 DESCRIPTION
   7      The zcons character driver exports the console for system zones.  The
   8      driver is fundamentally similar to a pseudo-terminal device, and is thus
   9      comprised of two sides:


  10 
  11      o   a manager device, which applications in the global zone can open for
  12          communication
  13 
  14      o   a subsidiary device, which processes in the non-global zone can write
  15          to, to communicate with global zone management applications



  16 
  17      Applications must not depend on the location of /dev or /devices entries
  18      exposed by zcons in the global zone.  Inside a non-global zone, the zcons
  19      subsidiary device is fronted by /dev/console and other console-related
  20      symbolic links, which are used by applications that expect to write to
  21      the system console.
  22 
  23      The zcons driver is not a Committed interface, and may change at any
  24      time.
