  Name:                                                         touch
 
  Synopsis:
        int touchwin(WINDOW *win);
        int touchline(WINDOW *win, int start, int count);
        int untouchwin(WINDOW *win);
        int wtouchln(WINDOW *win, int y, int n, int changed);
        bool is_linetouched(WINDOW *win, int line);
        bool is_wintouched(WINDOW *win);
 
  Description:
        touchwin() and touchline() throw away all information about
        which parts of the window have been touched, pretending that the
        entire window has been drawn on.  This is sometimes necessary
        when using overlapping windows, since a change to one window
        will affect the other window, but the records of which lines
        have been changed in the other window will not reflect the
        change.
 
        untouchwin() marks all lines in the window as unchanged since
        the last call to wrefresh().
 
        wtouchln() makes n lines in the window, starting at line y, look
        as if they have (changed == 1) or have not (changed == 0) been
        changed since the last call to wrefresh().
 
        is_linetouched() returns TRUE if the specified line in the
        specified window has been changed since the last call to
        wrefresh().
 
        is_wintouched() returns TRUE if the specified window
        has been changed since the last call to wrefresh().
 
  Return Value:
        All functions return OK on success and ERR on error except
        is_wintouched() and is_linetouched().
