.SH Description
.NXR "stty subroutine"
.NXA "stty subroutine" "ioctl system call"
.NXR "gtty subroutine"
.NXR "terminal" "setting state"
.NXR "terminal" "getting state"
This interface has been superseded by 
.MS ioctl 2 .
.PP
The
.PN stty
subroutine
sets the state of the terminal associated with
.IR fd .
The
.PN gtty
subroutine
retrieves the state of the terminal associated
with
.IR fd .
To set the state of a terminal the call must have
write permission.
.PP
The
.PN stty
call is actually ``ioctl(fd, TIOCSETP, buf)'', while
the
.PN gtty
call is ``ioctl(fd, TIOCGETP, buf)''.
See 
.MS ioctl 2
and
.MS tty 4
for an explanation.
.SH Return Values
If the call is successful 0 is returned, otherwise \-1 is
returned and the global variable
.I errno
contains the reason for the failure.
