How does capped-memory work in zones?

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 applica-
tions 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.
FILES
/dev/zcons/<zonename>/masterconsole
Global zone master side console for zone <zonename>.
/dev/zcons/<zonename>/slaveconsole
Global zone slave side console for zone <zonename>.
