SYNOPSIS
#include <form.h>
int set_form_opts(FORM *form, OPTIONS opts);
int form_opts_on(FORM *form, OPTIONS opts);
int form_opts_off(FORM *form, OPTIONS opts);
OPTIONS form_opts(const FORM *form);
DESCRIPTION
The function set_form_opts sets all the given form's option bits (form option bits may be logically-OR'ed together).
The function form_opts_on turns on the given option bits, and leaves others alone.
The function form_opts_off turns off the given option bits, and leaves others alone.
The function form_opts returns the form's current option bits.
The following options are defined (all are on by default):
- O_NL_OVERLOAD
- Overload the REQ_NEW_LINE forms driver request so that calling it at the end of a field goes to the next field.
- O_BS_OVERLOAD
- Overload the REQ_DEL_PREV forms driver request so that calling it at the beginning of a field goes to the previous field.
RETURN VALUE
Except for form_opts, each routine returns one of the following:
- E_OK
- The routine succeeded.
- E_SYSTEM_ERROR
- System error occurred (see errno).

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