    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 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_ 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 subwindow of menu.  

    RETURN VALUE

    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 (see errno).
    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.
     

    SEE ALSO

    curses(3X), menu(3X).  

    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.
