      setmenuwin sets the window of menu to win.  menuwin returns a pointer
      to the window of menu.

      setmenusub sets the subwindow of menu to sub.  menusub returns a
      pointer to the subwindow of menu.

      scalewindow returns the minimum window size necessary for the subwindow
      of menu.  rows and cols are pointers to the locations used to return the
      values.

      return an integer return one of the following:
      E_OK            - The routine returned successfully.
      E_SYSTEM_ERROR  - System error.
      E_BAD_ARGUMENT  - An incorrect argument was passed to the routine.
      E_POSTED        - The menu is already posted.
