stty(3)stty(3)NAME
stty, gtty - set and get terminal state
SYNOPSIS
#include <sgtty.h>
stty(
int fd,
struct sgttyb *buf ); gtty(
int fd,
struct sgttyb *buf );
DESCRIPTION
The stty() subroutine sets the state of the terminal associated with
fd. The gtty() subroutine retrieves the state of the terminal associ‐
ated with fd. To set the state of a terminal, the stty() call must have
write permission.
Calls to these subroutines, supported only to ensure BSD binary compat‐
ibility, have been superseded by the ioctl() system call. The stty()
call is implemented as ioctl(fd, TIOCSETP, buf), and the gtty() call is
implemented as ioctl(fd, TIOCGETP, buf). See ioctl(2) and tty(7) for
more information.
RETURN VALUES
If the call is successful, zero is returned; otherwise, -1 is returned
and the global variable errno indicates the reason for the failure.
