CURSES(3X) CURSES(3X) NAME curses - screen functions with ‘‘optimal’’ cursor motion SYNOPSIS cc [ flags ] files -lcurses -ltermcap [ libraries ] 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 _r_e_f_r_e_s_h_(_) tells the rou‐ tines to make the current screen look like the new one. In order to initialize the routines, the routine _i_n_i_t_s_c_r_(_) must be called before any of the other routines that deal with windows and screens are used. The routine _e_n_d_w_i_n_(_) should be called before exiting.
