form_post(3X)                                                    form_post(3X)

NAME
       post_form, unpost_form - 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(3X) 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.

RETURN VALUE
       These routines return one of the following:

       E_OK The routine succeeded.

       E_BAD_ARGUMENT
            Routine detected an incorrect or out-of-range argument.

       E_BAD_STATE
            Routine was called from an initialization or termination function.

       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
            The form has already been posted.

       E_SYSTEM_ERROR
            System error occurred (see errno(3)).

       The header file <form.h> automatically includes the header file
       <curses.h>.

PORTABILITY

       supported on Version 7 or BSD versions.
