NAME
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

The header file <form.h> automatically includes the header file <curses.h>. PORTABILITY
