post_form, unpost_form - write or erase forms from associated subwindows

#include <form.h>

int post_form(FORM **/form/);*
int unpost_form(FORM **/form/);*

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

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)).

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

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

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