C 5 stty, gtty - set and get terminal state (defunct)

 #include <sgtty.h>  stty(fd, buf)  int fd;  struct sgttyb *buf;  gtty(fd, buf)  int fd;  struct sgttyb *buf; 

This interface is obsoleted 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)'', while the gtty call is ``ioctl(fd, TIOCGETP, buf)''. See ioctl (2) and tty (4) for an explanation.

If the call is successful 0 is returned, otherwise -1 is returned and the global variable errno contains the reason for the failure. ioctl(2), tty(4)
