    NAME

    menu_format - set and get menu sizes
     
    

    SYNOPSIS

    #include <menu.h>
    int set_menu_format(MENU *menu, int rows, int cols);
    void menu_format(const MENU *menu, int *rows, int *cols);
     

    DESCRIPTION

    The function set_menu_format sets the maximum display size of the given menu. If this size is too small to display all menu items, the menu will be made scrollable. If this size is larger than the menus subwindow and the subwindow is too small to display all menu items, post_menu() will fail.

    The default format is 16 rows, 1 column. Calling set_menu_format with a null menu pointer will change this default. A zero row or column argument to set_menu_format is interpreted as a request not to change the current value.

    The function menu_format returns the maximum-size constraints for the given menu into the storage addressed by rows and cols.  

    RETURN VALUE

    These routines returns one of the following:
    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 is already 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.
