TTY(4) Linux Programmer's Manual TTY(4)
NAME
tty - controlling terminal
DESCRIPTION
The file /dev/tty is a character file with major number 5 and minor number 0, usually of mode 0666 and owner.group root.tty. It is a syn-
onym for the controlling terminal of a process, if any.
In addition to the ioctl(2) requests supported by the device that tty refers to, the ioctl(2) request TIOCNOTTY is supported.
TIOCNOTTY
Detach the calling process from its controlling terminal.
If the process is the session leader, then SIGHUP and SIGCONT signals are sent to the foreground process group and all processes in the
current session lose their controlling tty.
This ioctl(2) call only works on file descriptors connected to /dev/tty. It is used by daemon processes when they are invoked by a user at
a terminal. The process attempts to open /dev/tty. If the open succeeds, it detaches itself from the terminal by using TIOCNOTTY, while
if the open fails, it is obviously not attached to a terminal and does not need to detach itself.
FILES
/dev/tty
