set_form_opts, form_opts_on, form_opts_off, form_opts - set and get form options

#include <form.h>

int set_form_opts(FORM *form, Field_Options opts);
Field_Options form_opts(const FORM *form);

int form_opts_on(FORM *form, Field_Options opts);
int form_opts_off(FORM *form, Field_Options opts);

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):

5 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.

5 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:

5 E_OK The routine succeeded.

5 E_SYSTEM_ERROR System error occurred (see errno(3)).

These routines emulate the System V forms library. They were not supported on Version 7 or BSD versions. Juergen Pfeifer. Manual pages and adaptation for new curses by Eric S. Raymond. \%curses(3X), \%form(3X)
