NAME

       stty(), gtty() - control terminal device (Bell Version 6 compatibility)

SYNOPSIS

   Remarks
       These system calls are preserved for backward compatibility with Bell Version 6.  They provide as close an approximation as possible to the
       old Version 6 functions.  All new code should use the and calls described in termio(7).

DESCRIPTION

       For certain status settings and status inquiries about terminal devices, the functions and are equivalent to

       and

       respectively (see ioctl(2) and termio(7).

RETURN VALUE

       and return the following values:

	      Successful completion.
	      Failure.
		     is set to indicate the error.

ERRORS

       If or fails, is set to one of the following values:

       [EBADF]	      is not a valid file descriptor.

       [EFAULT]       points to an invalid address.

WARNINGS

   Obsolescent Interfaces
       and are to be obsoleted at a future date.

NAME

       ioctl, stty, gtty - control device

SYNOPSIS

       #include <sgtty.h>

       ioctl(fildes, request, argp)
       struct sgttyb *argp;

       stty(fildes, argp)
       struct sgttyb *argp;

       gtty(fildes, argp)
       struct sgttyb *argp;

DESCRIPTION

       Ioctl performs a variety of functions on character special files (devices).  The writeups of various devices in section 4 discuss how ioctl
       applies to them.

       For certain status setting and status inquiries about terminal devices, the functions stty and gtty are equivalent to
	      ioctl(fildes, TIOCSETP, argp)
	      ioctl(fildes, TIOCGETP, argp)

       respectively; see tty(4).

       The following two calls, however, apply to any open file:

	      ioctl(fildes, FIOCLEX, NULL);
	      ioctl(fildes, FIONCLEX, NULL);

       The first causes the file to be closed automatically during a successful exec operation; the second reverses the effect of the first.

SEE ALSO

       stty(1), tty(4), exec(2)

DIAGNOSTICS

       Zero is returned if the call was successful; -1 if the file descriptor does not refer to the kind of file for which it was intended.

BUGS

       Strictly speaking, since ioctl may be extended in different ways to devices with different properties, argp should have an open-ended  dec-
       laration like

	      union { struct sgttyb ...; ...  } *argp;

       The important thing is that the size is fixed by `struct sgttyb'.
