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.

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

E_NOT_POSTED

E_NOT_CONNECTED

E_NO_ROOM

E_POSTED

E_SYSTEM_ERROR

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.
