OCURSES(3)                 BSD Programmer's Manual                  OCURSES(3)

NAME

     ocurses - screen functions with ``optimal'' cursor motion

SYNOPSIS

     cc [flags] files -locurses [libraries]

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