NAME

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

LIBRARY

Compatibility Library (libcompat, -lcompat)

SYNOPSIS

#include <sgtty.h>

stty(int fd, struct sgttyb *buf);

gtty(int fd, struct sgttyb *buf);

DESCRIPTION

These interfaces are obsoleted by ioctl(2). They are available from the compatibility library, libcompat.

The stty() function sets the state of the terminal associated with fd. The gtty() function 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.

RETURN VALUES

The gtty() and stty() functions return the value 0 if successful; otherwise the value -1 is returned and the global variable errno is set to indicate the error.

HISTORY

The stty() and gtty() functions appeared in Version 1 AT&T UNIX. Obsoleted by ioctl(2), these functions were moved to libcompat in 4.2BSD.
