FORMS(3)			   BSD 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 character in the field
		    then the backspace character will perform 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.

SEE ALSO
     curses(3), forms(3)

NOTES
     The header <form.h> automatically includes both <curses.h> and <eti.h>.
