stty(3)
Name
stty, gtty − set and get terminal state
Syntax
#include <sgtty.h>
stty(fd, buf)
int fd;
struct sgttyb *buf;
gtty(fd, buf)
int fd;
struct sgttyb *buf;
Description
This interface has been superseded by ioctl(.).
The stty subroutine sets the state of the terminal associated with fd. The gtty subroutine 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() and tty() for an explanation.
Return Values
If the call is successful 0 is returned, otherwise −1 is returned and the global variable errno contains the reason for the failure.
