The
|
||
|
|
.BR gtty
|
||
|
|
function
|
||
|
|
retrieves the state of the terminal associated
|
||
|
|

||
|
|
.IR fd .
|
||
|
|
To set the state of a terminal the call must have

|
||
|
|
.LP
|
||
|
|
The
|
||
|
|
.BR stty
|
||
|
|
call is actually
|
||
|
|
.nf
|
||
|
|
|
||
|
|
ioctl(fd, TIOCSETP, buf);
|
||
|

|
||
|
|
.fi

|
while the
|
||
|
|
.BR gtty
|
||
|
|
call is
|
||
|
|
.nf
|
||
|
|
|
||
|
|
ioctl(fd, TIOCGETP, buf);
|
||
|

|
.IR errno
|
||
|
|
contains the reason for the failure.
