STTY(3C)
NAME
stty, gtty − set and get terminal state (defunct)
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)”, but the gtty call is “ioctl(fd, TIOCGETP, buf)”. See ioctl(2) and tty(4) for an explanation.
RETURN VALUE
If the call is successful, zero is returned; otherwise, −1 is returned and the global variable errno contains the reason for the failure.
