ocurses - screen functions with ``optimal'' cursor motion
cc [flags] files -locurses [libraries]
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 refresh() tells the
routines to make
the current screen look like the new one. In order to initialize the
routines, the routine initscr() must be called before any of
the other
routines that deal with windows and screens are used. The
routine
endwin() should be called before exiting.
