zcons(4D)

Name

zcons - Zone console device driver

Description

The zcons character driver exports the console for system zones. The driver is comprised of two "sides:" a master side with which applications in the global zone communicate, and a slave side, which receives I/O from the master side. The slave side is available in the global zones.

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

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