37 * An example of the 'filter()' function in ncurses, this program prompts
38 * for commands and executes them (like a command shell). It illustrates
39 * how ncurses can be used to implement programs that are not full-screen.
41 * Ncurses differs slightly from SVr4 curses. The latter does not flush its
42 * state when exiting program mode, so the attributes on the command lines of
43 * this program 'bleed' onto the executed commands. Rather than use the
44 * reset_shell_mode() and reset_prog_mode() functions, we could invoke endwin()
45 * and refresh(), but that does not work any better.
