FORMS(3)                NetBSD Library Functions Manual               FORMS(3)


NAME

     form_opts, form_opts_off, form_opts_on, set_form_opts -- form library


LIBRARY

     Curses Form Library (libform, -lform)


SYNOPSIS

     #include <form.h>

     Form_Options
     form_opts(FORM *form);

     int
     form_opts_off(FORM *form, Form_Options options);

     int
     form_opts_on(FORM *form, Form_Options options);

     int
     set_form_opts(FORM *form, Form_Options options);


DESCRIPTION

     The function form_opts() returns the current options that are set on the
     given form.  The form_opts_off() will turn off the form options given in
     options for the form, similarly, form_opts_on() will turn on the options
     specified in options for the given form.  The form options can be set to
     an explicit set by calling set_form_opts().


PARAMETERS

     The following form options are valid:

     O_BS_OVERLOAD  If this option is set and the cursor is at the first char-
                    acter in the field then the backspace character will per-
                    form the same function as a REQ_PREV_FIELD driver request,
                    moving to the previous field in the form.
     O_NL_OVERLOAD  If this option is set and the cursor is at the end of the
                    field then the new line character will perform the same
                    function as a REQ_NEXT_FIELD driver request, moving to the
                    next field in the form.

     By default no form options are set.


RETURN VALUES

     Functions returning pointers will return NULL if an error is detected.
     The functions that return an int will return one of the following error
     values:

     E_OK               The function was successful.
