+
+  Synopsis:
+        int def_prog_mode(void);
+        int def_shell_mode(void);
+        int reset_prog_mode(void);
+        int reset_shell_mode(void);
+        int resetty(void);
+        int savetty(void);
+        int ripoffline(int line, int (*init)(WINDOW *, int));
+        int curs_set(int visibility);
+        int napms(int ms);
+
+        int draino(int ms);
+        int resetterm(void);
+        int fixterm(void);
+        int saveterm(void);
+
+  Description:
+        def_prog_mode() and def_shell_mode() save the current terminal
+        modes as the "program" (in curses) or "shell" (not in curses)
+        state for use by the reset_prog_mode() and reset_shell_mode()
+        functions.  This is done automatically by initscr().
+
+        reset_prog_mode() and reset_shell_mode() restore the terminal to
+        "program" (in curses) or "shell" (not in curses) state.  These
+        are done automatically by endwin() and doupdate() after an
+        endwin(), so they would normally not be called before these
+        functions.
+
+        savetty() and resetty() save and restore the state of the
+        terminal modes. savetty() saves the current state in a buffer,
+        and resetty() restores the state to what it was at the last call
+        to savetty().
+
+        curs_set() alters the appearance of the cursor. A visibility of
+        0 makes it disappear; 1 makes it appear "normal" (usually an
+        underline) and 2 makes it "highly visible" (usually a block).
+
+        ripoffline() reduces the size of stdscr by one line.  If the
+        "line" parameter is positive, the line is removed from the top
+        of the screen; if negative, from the bottom. Up to 5 lines can
+        be ripped off stdscr by calling ripoffline() repeatedly. The
+        function argument, init, is called from within initscr() or
+        newterm(), so ripoffline() must be called before either of these
+        functions.  The init function receives a pointer to a one-line
+        WINDOW, and the width of the window. Calling ripoffline() with a
+        NULL init function pointer is an error.
+
+        napms() suspends the program for the specified number of
+        milliseconds. draino() is an archaic equivalent.
+
+        resetterm(), fixterm() and saveterm() are archaic equivalents
+        for reset_shell_mode(), reset_prog_mode() and def_prog_mode(),
+        respectively.
+
+  Return Value:
+        All functions return OK on success and ERR on error, except
+        curs_set(), which returns the previous visibility.
