DESCRIPTION    [Toc]    [Back]

       The function post_form displays a form to  its  associated
       subwindow.   To trigger physical display of the subwindow,
       use  refresh  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.
