NAME

       stty, gtty - set and get terminal state (defunct)

SYNOPSIS

       #include <sgtty.h>

       stty(fd, buf)
       int fd;
       struct sgttyb *buf;

       gtty(fd, buf)
       int fd;
       struct sgttyb *buf;

DESCRIPTION

       This interface is obsoleted by ioctl(2).

       Stty  sets the state of the terminal associated with fd.  Gtty retrieves the state of the terminal associated with fd.  To set the state of
       a terminal the call must have write permission.

       The stty call is actually ``ioctl(fd, TIOCSETP, buf)'', while the gtty call is ``ioctl(fd, TIOCGETP, buf)''.  See ioctl(2) and  tty(4)  for
       an explanation.

DIAGNOSTICS

       If the call is successful 0 is returned, otherwise -1 is returned and the global variable errno contains the reason for the failure.

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() requests supported by the device that tty refers to, the following ioctl() request is supported:

       TIOCNOTTY
	      Detach the current process from its controlling terminal, and remove it from its current process group, without attaching  it  to  a
	      new  process  group  (that  is,  set  its  process group ID to zero).  This ioctl() call only works on file descriptors connected to
	      /dev/tty; this 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.
