CURSES(3X)                                             CURSES(3X)

          curses - screen functions with `optimal' cursor motion

          cc args -lcurses -ltermcap

          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.  The initialization routine initscr()
          must be called before any other routines that deal with win-
          dows and screens.  The routine endwin() should be called
          before exiting.
