form_opts_on (3form)

#include <form.h>

int set_form_opts(FORM *form, Field_Options opts);

int form_opts_on(FORM *form, Field_Options opts);

int form_opts_off(FORM *form, Field_Options opts);

Field_Options form_opts(const FORM *form);

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.

Except for form_opts, each routine returns one of the following:

E_OK

The routine succeeded.

E_SYSTEM_ERROR

System error occurred (see errno).

ncurses(3NCURSES), form(3FORM).

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.
