   9 .SH DESCRIPTION
  10 .sp
  11 .LP
  12 The \fBzcons\fR character driver exports the console for system zones. The
  13 driver is comprised of two "sides:" a master side with which applications in
  14 the global zone communicate, and a slave side, which receives I/O from the
  15 master side. The slave side is available in the global zones.
  16 .sp
  17 .LP
  18 Applications must not depend on the location of \fB/dev\fR or \fB/devices\fR
  19 entries exported by \fBzcons\fR. Inside a zone, the \fBzcons\fR slave  side is
  20 fronted by \fB/dev/console\fR and other console-related  symbolic links, which
  21 are used by applications that expect to write to the system console.
  22 .sp
  23 .LP
  24 The \fBzcons\fR driver is Sun Private, and may change in future releases.

  11 .Nm zcons
  12 .Nd Zone console device driver
  13 .Sh DESCRIPTION
  14 The
  15 .Nm zcons
  16 character driver exports the console for system zones.
  17 The driver is fundamentally similar to a pseudo-terminal device, and is thus
  18 comprised of two sides:
  19 .Bl -bullet
  20 .It
  21 a manager device, which applications in the global zone can open for
  22 communication
  23 .It
  24 a subsidiary device, which processes in the non-global zone can write to, to
  25 communicate with global zone management applications
  26 .El
  27 .Pp
  28 Applications must not depend on the location of
  29 .Pa /dev
  30 or
  31 .Pa /devices
  32 entries exposed by
  33 .Nm zcons
  34 in the global zone.
  35 Inside a non-global zone, the
  36 .Nm zcons
  37 subsidiary device is fronted by
  38 .Pa /dev/console
  39 and other console-related symbolic links, which are used by applications that
  40 expect to write to the system console.
  41 .Pp
  42 The
  43 .Nm
  44 driver is not a
  45 .Sy Committed
  46 interface, and may change at any time.
