.TH CURSES 3X
.CT 2 comm_term
.SH NAME
curses \(mi screen functions with `optimal' cursor motion
.SH DESCRIPTION
These routines give the user a method
of updating screens with reasonable optimization.
They keep an image of the current screen,
and the user sets up an image of a new one.
Then
.I refresh()
tells the routines to make the current screen look
like the new one.
The initialization routine
.I initscr()
must be called before any other routines
that deal with windows and screens.
The routine
.I endwin()
should be called before exiting.
.PP
To load the functions use the
.IR ld (1)
options
.BR \-lcurses\ \-ltermcap .
.SH SEE ALSO
.IR ioctl (2),
.IR termcap (5)
