.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 the
|
|
|
|
|
.Fn refresh
|
|
|
|
|
tells the routines to make the current screen look like the new one.
|
|
|
|
|
In order to initialize the routines, the routine
|
|
|
|
|
.Fn initscr
|
|
|
|
|
must be called before any of the other routines that deal with windows and
|
|
|
|
|
screens are used. The routine
|
|
|
|
|
.Fn endwin
|
|
|
|
|
should be called before exiting.
