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)).

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.
