STTY(3C)
NAME
stty, gtty − set/get terminal state (obsolete)
USAGE
#include <sgtty.h>
stty(fd, buf) int fd; struct sgttyb *buf;
gtty(fd, buf) int fd; struct sgttyb *buf;
DESCRIPTION
This interface has been made obsolete 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) and the gtty call is ioctl(fd, TIOCGETP, buf) See ioctl(2) and tty(4) for explanations.
RETURN VALUE
A successful call returns zero. A failed call returns -1 and sets errno.
