NAME

       form_post - write or erase forms from associated subwindows

SYNOPSIS

       #include <form.h>
       int post_form(FORM *form);
       int unpost_form(FORM *form);

DESCRIPTION

       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.

       These routines return one of the following:

       E_OK The routine succeeded.

       E_BAD_ARGUMENT

       E_BAD_STATE
            Routine was called from an initialization or termination function.

       E_NOT_POSTED

       E_NOT_CONNECTED
            No items are connected to the form.

       E_NO_ROOM
            Form is too large for its window.

       E_POSTED
            The form has already been posted.
