ncurses -> the best way to use menus

hello there,

i'm exploring the curses lib and i'm having some trouble with "defining a style". to clarify: i'm creating a menu driven app and i've been thinking what's the best way to use menus: make global vars (not my favourite), creating a function which designs the menu and returns the selected option (doesn't seem the best either). can someone point me some code to use as example or give me some hint?

basically what i want to do is to create a menu which calls a submenu and then the submenu calls a function. also, i'm using scr_dump to save the screen, can't i do this without having to save the screen?

thx in advance Smilie

unpost_menu

post(3MENU)															       post(3MENU)

NAME

       post - write or erase menus from associated subwindows

SYNOPSIS

       #include <menu.h>
       int post_menu(MENU *menu);
       int unpost_menu(MENU *menu);

DESCRIPTION

       The  function  post_menu  displays  a  menu to its associated subwindow.  To trigger physical display of the subwindow, use refresh or some
       equivalent curses routine (the implicit doupdate triggered by an curses input request will do). post_menu resets the  selection	status	of
       all items.

       The function unpost_menu erases menu from its associated subwindow.

RETURN VALUE

       These routines return one of the following:

       E_OK The routine succeeded.

       E_SYSTEM_ERROR
	    System error occurred (see errno).

       E_BAD_ARGUMENT
	    Routine detected an incorrect or out-of-range argument.

       E_POSTED
	    The menu has already been posted.

       E_BAD_STATE
	    Routine was called from an initialization or termination function.

       E_NO_ROOM
	    Menu is too large for its window. You should consider to use set_menu_format() to solve the problem.

       E_NOT_POSTED
	    The menu has not been posted.

       E_NOT_CONNECTED
	    No items are connected to the menu.

SEE ALSO

       ncurses(3NCURSES), menu(3MENU).

NOTES

       The header file <menu.h> automatically includes the header file <curses.h>.

PORTABILITY

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