CURSES(3)                      Library Routines                      CURSES(3)




NAME

       curses - screen functions with ''optimal


SYNOPSIS

       occ -flags -L/usr/lib files -llibcurses -llibtermcap


DESCRIPTION

       These  routines give the user a method of updating screens with reason-
       able optimization.  They keep an image of the current screen,  and  the
       user  sets  up  an image of a new one.  Then the refresh tells the rou-
       tines 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.
