NAME
opts - set and get form options
SYNOPSIS
#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);
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

PORTABILITY
