12 The menu library provides terminal-independent facilities for composing
13 menu systems on character-cell terminals. The library includes: item
14 routines, which create and modify menu items; and menu routines, which
15 group items into menus, display menus on the screen, and handle inter‐
16 action with the user.
17 The menu library uses the curses libraries, and a curses initialization
19 routine such as initscr must be called before using any of these func‐
20 tions. To use the menu library, link with the options -lmenu -lcurses.
21 Current Default Values for Item Attributes
23 The menu library maintains a default value for item attributes. You
24 can get or set this default by calling the appropriate get_ or set_
25 routine with a NULL item pointer. Changing this default with a set_
26 function affects future item creations, but does not change the render‐
27 ing of items already created.
28 Routine Name Index
30 The following table lists each menu routine and the name of the manual
31 page on which it is described.

102 Routines that return pointers return NULL on error. Routines that
103 return an integer return one of the following error codes:
104 E_OK The routine succeeded.
106 E_BAD_ARGUMENT
108 Routine detected an incorrect or out-of-range argument.
109 E_BAD_STATE
111 Routine was called from an initialization or termination function.
112 E_NO_MATCH
114 Character failed to match.
115 E_NO_ROOM
117 Menu is too large for its window.
118 E_NOT_CONNECTED
120 No items are connected to the menu.
121 E_NOT_POSTED
123 The menu has not been posted.
124 E_NOT_SELECTABLE
126 The designated item cannot be selected.
127 E_POSTED
129 The menu is already posted.
130 E_REQUEST_DENIED
132 The menu driver could not process the request.
133 E_SYSTEM_ERROR
135 System error occurred (see errno).
136 E_UNKNOWN_COMMAND
138 The menu driver code saw an unknown request code.
139
141 The header file <menu.h> automatically includes the header files
142 <curses.h> and <eti.h>.
143 In your library list, libmenu.a should be before libncurses.a; that is,
145 you should say “-lmenu -lncurses”, not the other way around (which
146 would give a link-error when using static libraries).
147
149 These routines emulate the System V menu library. They were not sup‐
150 ported on Version 7 or BSD versions.
151 The menu facility was documented in SVr4.2 in Character User Interface
153 Programming (UNIX SVR4.2).
154 It is not part of X/Open Curses.
156 Aside from ncurses, there are few implementations:
158 · systems based on SVr4 source code, e.g., Solaris.
160 · NetBSD curses.
