       Juergen Pfeifer.  Manual pages and adaptation for new curses by Eric S. Raymond.

       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.

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

       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)).
