The library includes: item routines, which create and mod- ify menu items; and menu routines, which group items into menus, display menus on the screen, and handle interaction with the user. The <STRONG>menu</STRONG> library uses the <STRONG>curses</STRONG> libraries, and a curses initialization routine such as <STRONG>initscr</STRONG> must be called before using any of these functions. To use the <STRONG>menu</STRONG> library, link with the options <STRONG>-lmenu</STRONG> <STRONG>-lcurses</STRONG>. <STRONG>Current</STRONG> <STRONG>Default</STRONG> <STRONG>Values</STRONG> <STRONG>for</STRONG> <STRONG>Item</STRONG> <STRONG>Attributes</STRONG> The <STRONG>menu</STRONG> library maintains a default value for item attributes. You can get or set this default by calling the appropriate <STRONG>get_</STRONG> or <STRONG>set_</STRONG> routine with a <STRONG>NULL</STRONG> item pointer. Changing this default with a <STRONG>set_</STRONG> function affects future item creations, but does not change the rendering of items already created. <STRONG>Routine</STRONG> <STRONG>Name</STRONG>

return <STRONG>NULL</STRONG> on error. Rou- tines that return an integer return one of the following error codes: <STRONG>E_OK</STRONG> The routine succeeded. <STRONG>E_SYSTEM_ERROR</STRONG> System error occurred (see <STRONG>errno</STRONG>). <STRONG>E_BAD_ARGUMENT</STRONG> Routine detected an incorrect or out-of-range argu- ment. <STRONG>E_POSTED</STRONG> The menu is already posted. <STRONG>E_BAD_STATE</STRONG> Routine was called from an initialization or termina- tion function. <STRONG>E_NO_ROOM</STRONG> Menu is too large for its window. <STRONG>E_NOT_POSTED</STRONG> The menu has not been posted. <STRONG>E_UNKNOWN_COMMAND</STRONG> The menu driver code saw an unknown request code. <STRONG>E_NO_MATCH</STRONG> Character failed to match. <STRONG>E_NOT_SELECTABLE</STRONG> The designated item cannot be selected. <STRONG>E_NOT_CONNECTED</STRONG> No items are connected to the menu. <STRONG>E_REQUEST_DENIED</STRONG> The menu driver could not process the request.</PRE><H2>SEE ALSO</H2><PRE> <STRONG><A HREF="ncurses.3x.html">curses(3x)</A></STRONG> and related pages whose names begin "menu_" for detailed descriptions of the entry points.</PRE><H2>NOTES</H2><PRE> The header file <STRONG><menu.h></STRONG> automatically includes the header files <STRONG><curses.h></STRONG> and <STRONG><eti.h></STRONG>. In your library list, libmenu.a should be before libn- curses.a; that is, you want to say `-lmenu -lncurses', not the other way around (which would give you a link error using GNU <STRONG><A HREF="ld.1.html">ld(1)</A></STRONG> and many other linkers).</PRE><H2>PORTABILITY</H2><PRE> These routines emulate the System V menu library. They were not supported on Version 7 or BSD versions.</PRE><H2>AUTHORS</H2><PRE> Juergen Pfeifer. Manual pages and adaptation for ncurses by Eric S.
