# form_opts 3x

    form_opts(3x)                                                    form_opts(3x)

## NAME

           set_form_opts,  form_opts_on,  form_opts_off,  form_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(3)).

## SEE ALSO

           curses(3x), form(3x).

## NOTES

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

## PORTABILITY

           These routines emulate the System V forms library.  They were not  sup-
           ported on Version 7 or BSD versions.
