menu - curses extension for programming menus
#include <menu.h>
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 rendering 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.
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_SYSTEM_ERROR
System error occurred (see errno).
E_BAD_ARGUMENT
Routine detected an incorrect or out-of-range argument.
E_POSTED
The menu is already posted.
E_BAD_STATE
Routine was called from an initialization or termination function.
E_NO_ROOM
Menu is too large for its window.
E_NOT_POSTED
The menu has not been posted.
E_UNKNOWN_COMMAND
The menu driver code saw an unknown request code.
E_NO_MATCH
Character failed to match.
E_NOT_SELECTABLE
The designated item cannot be selected.
E_NOT_CONNECTED
No items are connected to the menu.
E_REQUEST_DENIED
The menu driver could not process the request.
curses(3X) and related pages whose names begin "menu_" for detailed descriptions of the entry points.
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).
These routines emulate the System V menu library. They were not supported on Version 7 or BSD versions.
