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)).

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 supported on  Version  7
       or BSD versions.
