.Fd gettmode
|

.De
|
|
Get the tty stats.
|
|
This is normally called by
|
|
.Fn initscr .

.Ds
|
|
.Fd mvcur lasty\*,lastx\*,newy\*,newx
|
|
int lasty\*,lastx\*,newy\*,newx;

.De
|
|
Moves the terminal's cursor from
|
|
.Vn lasty\*,lastx ) (
|
|
to
|
|
.Vn newy\*,newx ) (
|
|
in an approximation of optimal fashion.
|
|
This routine uses the functions borrowed from
|
|
.i ex
|
|
version 2.6.
|
|
It is possible to use this optimization
|
|
without the benefit of the screen routines.
|
|
With the screen routines, this should not be called by the user.
|
|
.Fn move
|
|
and
|
|
.Fn refresh
|
|
should be used to move the cursor position,
|
|
so that the routines know what's going on.
|
|
.Ds
|
|
.Fd scroll win
|
|
WINDOW *win;
|
|
.De
|
|
Scroll the window upward one line.
|
|
This is normally not used by the user.

|
|
.Fd savetty "" \*m
|
|
.Fd resetty "" \*m
|
|
.De
|
|
.Fn savetty
|
|
saves the current tty characteristic flags.
|
|
.Fn resetty
|
|
restores them to what
|
|
.Fn savetty
|
|
stored.
|
|
These functions are performed automatically by
|
|
.Fn initscr
|
|
and
|
|
.Fn endwin .
|
|
.Ds
|
|
.Fd setterm name
|
|
char *name;
|
|
.De
|
|
Set the terminal characteristics to be those of the terminal named
|
|
.Vn name ,
|
|
getting the terminal size from the
|
|
.b TIOCGWINSZ
|
|
.Fn ioctl "" "" 2
|
|
if it exists,
|
|
otherwise from the environment.
|
|
This is normally called by
|
|
.Fn initscr .
|
|
.Ds
|
|
.Fd tstp
|
|
.De
|
|
If the new
|
|
.b tty (4)
|
|
driver is in use,
|
|
this function
|
|
will save the current tty state
|
|
and then put the process to sleep.
|
|
When the process gets restarted,
|
|
it restores the tty state
|
|
and then calls
|
|
.Fn wrefresh "" "" curscr
|
|
to redraw the screen.
|
|
.Fn initscr
|
|
sets the signal
|
|
SIGTSTP
|
|
to trap to this routine.
