NAME

       menu - curses extension for programming menus

SYNOPSIS

       #include <menu.h>

DESCRIPTION

       The  menu  library  provides terminal-independent facilities for composing menu systems on character-cell terminals.  The library includes:
       item routines, which create and modify menu items; and menu routines, which group items into menus, display menus on the screen, and handle
       interaction with the user.

       The  menu  library  uses the curses libraries, and a curses initialization routine such as initscr must be called before using any of these
       functions.  To use the menu library, link with the options -lmenu -lcurses.

   Current Default Values for Item Attributes
       The menu library maintains a default value for item attributes.	You can get or set this default by calling the appropriate  get_  or  set_
       routine	with  a NULL item pointer.  Changing this default with a set_ function affects future item creations, but does not change the ren-
       dering of items already created.

   Routine Name Index
       The following table lists each menu routine and the name of the manual page on which it is described.

RETURN VALUE

       Routines that return pointers return NULL on error.  Routines that return an integer return one of the following error codes:

       E_OK The routine succeeded.

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

       E_BAD_STATE
	    Routine was called from an initialization or termination function.

       E_NO_MATCH
	    Character failed to match.

       E_NO_ROOM
	    Menu is too large for its window.

       E_NOT_CONNECTED
	    No items are connected to the menu.

       E_NOT_POSTED
	    The menu has not been posted.

       E_NOT_SELECTABLE
	    The designated item cannot be selected.

       E_POSTED
	    The menu is already posted.

       E_REQUEST_DENIED
	    The menu driver could not process the request.

       E_SYSTEM_ERROR
	    System error occurred (see errno).

       E_UNKNOWN_COMMAND
	    The menu driver code saw an unknown request code.

SEE ALSO

       ncurses(3NCURSES) and related pages whose names begin "menu_" for detailed descriptions of the entry points.

NOTES

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

       In your library list, libmenu.a should be before libncurses.a; that is, you want to say `-lmenu -lncurses', not the other way around (which
       would usually give a link-error).

PORTABILITY

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