NAME

6       form_opts - set and get form options
7

SYNOPSIS

9       #include <form.h>
10       int set_form_opts(FORM *form, Field_Options opts);
11       int form_opts_on(FORM *form, Field_Options opts);
12       int form_opts_off(FORM *form, Field_Options opts);
13       Field_Options form_opts(const FORM *form);
14

DESCRIPTION

16       The  function set_form_opts sets all the given form's option bits (form
17       option bits may be logically-OR'ed together).
18
19       The function form_opts_on turns on the given option  bits,  and  leaves
20       others alone.
21
22       The  function form_opts_off turns off the given option bits, and leaves
23       others alone.
24
25       The function form_opts returns the form's current option bits.
26
27       The following options are defined (all are on by default):
28
29       O_NL_OVERLOAD
30            Overload the REQ_NEW_LINE forms driver request so that calling  it
31            at the end of a field goes to the next field.
32
33       O_BS_OVERLOAD
34            Overload  the REQ_DEL_PREV forms driver request so that calling it
35            at the beginning of a field goes to the previous field.
36
