menu_win(3X) Library calls menu_win(3X) NAME menu_win - make and break menu window and subwindow associations SYNOPSIS #include <menu.h> int set_menu_win(MENU *menu, WINDOW *win); WINDOW *menu_win(const MENU *menu); int set_menu_sub(MENU *menu, WINDOW *sub); WINDOW *menu_sub(const MENU *menu); int scale_menu(const MENU *menu, int *rows, int *columns); DESCRIPTION Every menu has an associated pair of curses windows. The menu window displays any title and border associated with the window; the menu sub- window displays the items of the menu that are currently available for selection. The first four functions get and set those windows. It is not neces- sary to set either window; by default, the driver code uses stdscr for both. In the set_ functions, window argument of NULL is treated as though it were stsdcr. A menu argument of NULL is treated as a request to change the system default menu window or subwindow. The function scale_menu returns the minimum size required for the sub- window of menu. RETURN VALUE Routines that return pointers return NULL on error. Routines that re- turn an integer return one of the following error codes: E_OK The routine succeeded. E_SYSTEM_ERROR System error occurred (see errno(3)). E_BAD_ARGUMENT Routine detected an incorrect or out-of-range argument. E_POSTED The menu has already been posted. E_NOT_CONNECTED No items are connected to the menu. PORTABILITY These routines emulate the System V menu library. They were not sup- ported on Version 7 or BSD versions. AUTHORS Juergen Pfeifer. Manual pages and adaptation for new curses by Eric S.
