PURPOSE

Supports the controlling terminal interface.

SYNOPSIS

#include<sys/hft.h>
#include<sys/termio.h>
#include<sys/tty.h>

DESCRIPTION

For each process, the /dev/tty special file is a synonym for the associated
control terminal.  It is found in all AIX systems.  This file is useful to
programs or shell sequences that wish to ensure writing messages on the
terminal regardless of how output is redirected.  It can also be used for
programs that demand the name of a file for output when typed output is
desired, and to find out what terminal is currently in use.

FILES

/dev/tty
/dev/tty*
