A program using these routines must be compiled with \fB-lmenu\fR and \fB-lcurses\fR on the \fBcc\fR command line. .sp .LP The menus package gives the applications programmer a terminal-independent method of creating and customizing menus for user interaction. The menus package includes: item routines, which are used to create and customize menu items; and menu routines, which are used to create and customize menus, assign pre- and post-processing routines, and display and interact with menus. .SS "Current Default Values for Item Attributes" The menus package establishes initial current default values for item attributes. During item initialization, each item attribute is assigned the current default value for that attribute. An application can change or retrieve a current default attribute value by calling the appropriate set or retrieve routine with a \fINULL\fR item pointer. If an application changes a current default item attribute value, subsequent items created using \fBnew_item()\fR will have the new default attribute value. The attributes of previously created items are not changed if a current default attribute value is changed. .SS "Routine Name Index" The following table lists each menus routine and the name of the manual page on which it is described. .sp .sp .TS c c l l . \fBMenus Routine Name\fR \fBManual Page Name\fR \fBcurrent_item\fR \fBmenu_item_current(3CURSES)\fR \fBfree_item\fR \fBmenu_item_new(3CURSES)\fR \fBfree_menu\fR \fBmenu_new(3CURSES)\fR \fBitem_count\fR \fBmenu_items(3CURSES)\fR \fBitem_description\fR \fBmenu_item_name(3CURSES)\fR \fBitem_index\fR \fBmenu_item_current(3CURSES)\fR \fBitem_init\fR \fBmenu_hook(3CURSES)\fR \fBitem_name\fR \fBmenu_item_name(3CURSES)\fR \fBitem_opts\fR \fBmenu_item_opts(3CURSES)\fR \fBitem_opts_off\fR \fBmenu_item_opts(3CURSES)\fR \fBitem_opts_on\fR \fBmenu_item_opts(3CURSES)\fR \fBitem_term\fR \fBmenu_hook(3CURSES)\fR \fBitem_userptr\fR \fBmenu_item_userptr(3CURSES)\fR \fBitem_value\fR \fBmenu_item_value(3CURSES)\fR \fBitem_visible\fR \fBmenu_item_visible(3CURSES)\fR \fBmenu_back\fR \fBmenu_attributes(3CURSES)\fR \fBmenu_driver\fR \fBmenu_driver(3CURSES)\fR \fBmenu_fore\fR \fBmenu_attributes(3CURSES)\fR \fBmenu_format\fR \fBmenu_format(3CURSES)\fR \fBmenu_grey\fR \fBmenu_attributes(3CURSES)\fR \fBmenu_init\fR \fBmenu_hook(3CURSES)\fR \fBmenu_items\fR \fBmenu_items(3CURSES)\fR \fBmenu_mark\fR \fBmenu_mark(3CURSES)\fR \fBmenu_opts\fR \fBmenu_opts(3CURSES)\fR \fBmenu_opts_off\fR \fBmenu_opts(3CURSES)\fR \fBmenu_opts_on\fR \fBmenu_opts(3CURSES)\fR \fBmenu_pad\fR \fBmenu_attributes(3CURSES)\fR \fBmenu_pattern\fR \fBmenu_pattern(3CURSES)\fR \fBmenu_sub\fR \fBmenu_win(3CURSES)\fR \fBmenu_term\fR \fBmenu_hook(3CURSES)\fR \fBmenu_userptr\fR \fBmenu_userptr(3CURSES)\fR \fBmenu_win\fR \fBmenu_win(3CURSES)\fR \fBnew_item\fR \fBmenu_item_new(3CURSES)\fR \fBnew_menu\fR \fBmenu_new(3CURSES)\fR \fBpos_menu_cursor\fR \fBmenu_cursor(3CURSES)\fR \fBpost_menu\fR \fBmenu_post(3CURSES)\fR \fBscale_menu\fR \fBmenu_win(3CURSES)\fR \fBset_current_item\fR \fBmenu_item_current(3CURSES)\fR \fBset_item_init\fR \fBmenu_hook(3CURSES)\fR \fBset_item_opts\fR \fBmenu_item_opts(3CURSES)\fR \fBset_item_term\fR \fBmenu_hook(3CURSES)\fR \fBset_item_userptr\fR \fBmenu_item_userptr(3CURSES)\fR \fBset_item_value\fR \fBmenu_item_value(3CURSES)\fR \fBset_menu_back\fR \fBmenu_attributes(3CURSES)\fR \fBset_menu_fore\fR \fBmenu_attributes(3CURSES)\fR \fBset_menu_format\fR \fBmenu_format(3CURSES)\fR \fBset_menu_grey\fR \fBmenu_attributes(3CURSES)\fR \fBset_menu_init\fR \fBmenu_hook(3CURSES)\fR \fBset_menu_items\fR \fBmenu_items(3CURSES)\fR \fBset_menu_mark\fR \fBmenu_mark(3CURSES)\fR \fBset_menu_opts\fR \fBmenu_opts(3CURSES)\fR \fBset_menu_pad\fR \fBmenu_attributes(3CURSES)\fR \fBset_menu_pattern\fR \fBmenu_pattern(3CURSES)\fR \fBset_menu_sub\fR \fBmenu_win(3CURSES)\fR \fBset_menu_term\fR \fBmenu_hook(3CURSES)\fR \fBset_menu_userptr\fR \fBmenu_userptr(3CURSES)\fR \fBset_menu_win\fR \fBmenu_win(3CURSES)\fR \fBset_top_row\fR \fBmenu_item_current(3CURSES)\fR \fBtop_row\fR \fBmenu_item_current(3CURSES)\fR \fBunpost_menu\fR \fBmenu_post(3CURSES)\fR .TE .SH RETURN VALUES Routines that return pointers always return \fINULL\fR on error.
