post_form, unpost_form - write or erase forms from associated subwindows

       Juergen Pfeifer.  Manual pages and adaptation for new curses by Eric S. Raymond.

       The  function  post_form displays a form to its associated subwindow.  To trigger physical display of the
       subwindow, use refresh(3NCURSES) or some equivalent curses routine (the implicit doupdate triggered by an
       curses input request will do).

       The function unpost_form erases form from its associated subwindow.
