menu_win()

make and break menu window and subwindow associations 

Curses Function


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 subwindow displays the items of the menu that are currently available for selection.

The first four functions get and set those windows. It is not necessary to set either window; by default, the driver code uses stdscr for both.

In the set_ chars, window argument of NULL is treated as though it were stdscr. 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 subwindow of menu.


RETURN VALUES

Routines that return pointers return NULL on error. Routines that return an integer return one of the following error codes:

E_OK 

The routine succeeded.

E_SYSTEM_ERROR 

System error occurred.

E_BAD_ARGUMENT 

Routine detected an incorrect or out-of-range argument.

E_POSTED 

The menu is already posted.

E_NOT_CONNECTED 

No items are connected to the menu.


NOTES

The header file <menu.h> automatically includes the header file <curses.h>.


PORTABILITY

These routines emulate the System V menu library. They were not supported on Version 7 or BSD versions.
