They are available from the compatibility library, libcompat. .Ef .Pp The .Fn stty function sets the state of the terminal associated with .Fa fd . The .Fn gtty function retrieves the state of the terminal associated with .Fa fd . To set the state of a terminal the call must have write permission. .Pp The .Fn stty call is actually .Ql ioctl(fd, TIOCSETP, buf) , while the .Fn gtty call is .Ql ioctl(fd, TIOCGETP, buf) . See .Xr ioctl 2 and .Xr tty 4 for an explanation. .Sh DIAGNOSTICS If the call is successful 0 is returned, otherwise \-1 is returned and the global variable .Va errno contains the reason for the failure. .Sh SEE ALSO .Xr ioctl 2 , .Xr tty 4 .Sh HISTORY The .Fn stty and .Fn gtty functions appeared in .At v1 . Obsoleted by .Xr ioctl 2 , these functions were moved to libcompat in .Bx 4.2 .
