NAME
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.

- E_NOT_POSTED
- The form has not been posted.
- E_NOT_CONNECTED
- No items are connected to the form.
- E_NO_ROOM
- Form is too large for its window.
- E_POSTED

- E_SYSTEM_ERROR
- System error occurred (see errno).
