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. .PP The \fBmenu\fR library uses the \fBcurses\fR libraries, and a curses initialization routine such as \fBinitscr\fR must be called before using any of these functions. To use the \fBmenu\fR library, link with the options \fB-lmenu -lcurses\fR. . .SS Current Default Values for Item Attributes . The \fBmenu\fR library maintains a default value for item attributes. You can get or set this default by calling the appropriate \fBget_\fR or \fBset_\fR routine with a \fBNULL\fR item pointer. Changing this default with a \fBset_\fR function affects future item creations, but does not change the rendering of items already created. . .SS Routine Name Index . The following table lists each \fBmenu\fR routine and the name of the manual page on which it is described. . .TS l l . \fBcurses\fR Routine Name Manual Page Name = current_item \fBmitem_current\fR(3X) free_item \fBmitem_new\fR(3X) free_menu \fBmenu_new\fR(3X) item_count \fBmenu_items\fR(3X) item_description \fBmitem_name\fR(3X) item_index \fBmitem_current\fR(3X) item_init \fBmenu_hook\fR(3X) item_name \fBmitem_name\fR(3X) item_opts \fBmitem_opts\fR(3X) item_opts_off \fBmitem_opts\fR(3X) item_opts_on \fBmitem_opts\fR(3X) item_term \fBmenu_hook\fR(3X) item_userptr \fBmitem_userptr\fR(3X) item_value \fBmitem_value\fR(3X) item_visible \fBmitem_visible\fR(3X) menu_back \fBmenu_attributes\fR(3X) menu_driver \fBmenu_driver\fR(3X) menu_fore \fBmenu_attributes\fR(3X) menu_format \fBmenu_format\fR(3X) menu_grey \fBmenu_attributes\fR(3X) menu_init \fBmenu_hook\fR(3X) menu_items \fBmenu_items\fR(3X) menu_mark \fBmenu_mark\fR(3X) menu_opts \fBmenu_opts\fR(3X) menu_opts_off \fBmenu_opts\fR(3X) menu_opts_on \fBmenu_opts\fR(3X) menu_pad \fBmenu_attributes\fR(3X) menu_pattern \fBmenu_pattern\fR(3X) menu_request_by_name \fBmenu_requestname\fR(3X) menu_request_name \fBmenu_requestname\fR(3X) menu_spacing \fBmenu_spacing\fR(3X) menu_sub \fBmenu_win\fR(3X) menu_term \fBmenu_hook\fR(3X) menu_userptr \fBmenu_userptr\fR(3X) menu_win \fBmenu_win\fR(3X) new_item \fBmitem_new\fR(3X) new_menu \fBmenu_new\fR(3X) pos_menu_cursor \fBmenu_cursor\fR(3X) post_menu \fBmenu_post\fR(3X) scale_menu \fBmenu_win\fR(3X) set_current_item \fBmitem_current\fR(3X) set_item_init \fBmenu_hook\fR(3X) set_item_opts \fBmitem_opts\fR(3X) set_item_term \fBmenu_hook\fR(3X) set_item_userptr \fBmitem_userptr\fR(3X) set_item_value \fBmitem_value\fR(3X) set_menu_back \fBmenu_attributes\fR(3X) set_menu_fore \fBmenu_attributes\fR(3X) set_menu_format \fBmenu_format\fR(3X) set_menu_grey \fBmenu_attributes\fR(3X) set_menu_init \fBmenu_hook\fR(3X) set_menu_items \fBmenu_items\fR(3X) set_menu_mark \fBmenu_mark\fR(3X) set_menu_opts \fBmitem_opts\fR(3X) set_menu_pad \fBmenu_attributes\fR(3X) set_menu_pattern \fBmenu_pattern\fR(3X) set_menu_spacing \fBmenu_spacing\fR(3X) set_menu_sub \fBmenu_win\fR(3X) set_menu_term \fBmenu_hook\fR(3X) set_menu_userptr \fBmenu_userptr\fR(3X) set_menu_win \fBmenu_win\fR(3X) set_top_row \fBmitem_current\fR(3X) top_row \fBmitem_current\fR(3X) unpost_menu \fBmenu_post\fR(3X) .TE .SH RETURN VALUE Routines that return pointers return \fBNULL\fR on error. Routines that return an integer return one of the following error codes: .TP 5 .B E_OK The routine succeeded. .TP 5 .B E_BAD_ARGUMENT Routine detected an incorrect or out-of-range argument. .TP 5 .B E_BAD_STATE Routine was called from an initialization or termination function. .TP 5 .B E_NO_MATCH Character failed to match. .TP 5 .B E_NO_ROOM Menu is too large for its window. .TP 5 .B E_NOT_CONNECTED No items are connected to the menu. .TP 5 .B E_NOT_POSTED The menu has not been posted. .TP 5 .B E_NOT_SELECTABLE The designated item cannot be selected. .TP 5 .B E_POSTED The menu is already posted. .TP 5 .B E_REQUEST_DENIED The menu driver could not process the request. .TP 5 .B E_SYSTEM_ERROR System error occurred (see \fBerrno\fR). .TP 5 .B E_UNKNOWN_COMMAND The menu driver code saw an unknown request code. .SH SEE ALSO \fBcurses\fR(3X) and related pages whose names begin "menu_" for detailed descriptions of the entry points. .SH NOTES The header file \fB<menu.h>\fR automatically includes the header files \fB<curses.h>\fR and \fB<eti.h>\fR. .PP 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). .SH PORTABILITY These routines emulate the System V menu library. They were not supported on Version 7 or BSD versions. .SH AUTHORS Juergen Pfeifer. Manual pages and adaptation for ncurses by Eric S. Raymond. .SH SEE ALSO This describes \fBncurses\fR version @NCURSES_MAJOR@.@NCURSES_MINOR@ (patch @NCURSES_PATCH@). .\"# .\"# The following sets edit modes for GNU EMACS .\"# Local Variables: .\"# mode:nroff .\"# fill-column:79 .\"# End:
