form_win - make and break form window and subwindow associa-
tions
#include <form.h>
int set_form_win(FORM *form, WINDOW *win);
WINDOW *form_win(const FORM *form);
int set_form_sub(FORM *form, WINDOW *sub);
WINDOW *form_sub(const FORM *form);
int scale_form(const FORM *form, int *rows, int *columns);
Every form has an associated pair of curses windows. The
form window displays any title and border associated with
the window; the form subwindow displays the items of the
form that are currently available for selection.
The first four functions get and set those windows. It is
not necessary to set either window; by default, the driver
code uses stdscr for both.
In the set_ functions, window argument of NULL is treated as
though it were stsdcr. A form argument of NULL is treated
as a request to change the system default form window or
subwindow.
The function scale_form returns the minimum size required
for the subwindow of form.
Routines that return pointers return NULL on error. Rou-
tines that return an integer return one of the following
error codes:
E_OK The routine succeeded.
E_SYSTEM_ERROR
System error occurred (see errno).
E_BAD_ARGUMENT
Routine detected an incorrect or out-of-range argument.
E_POSTED
The form has already been posted.
E_NOT_CONNECTED
No items are connected to the form.

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.
