form_post(3X)

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.

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).

curses(3X), form(3X).

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

PORTABILITY
These routines emulate the System V forms library. They were not supported on Version 7 or BSD versions.
