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).


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.
