menu_format(3X)               Library calls               menu_format(3X)

NAME         top

       set_menu_format, menu_format - set and get menu sizes

SYNOPSIS         top

       #include <menu.h>

       int set_menu_format(MENU *menu, int rows, int cols);
       void menu_format(const MENU *menu, int *rows, int *cols);

DESCRIPTION         top

       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         top

       These routines returns one of the following:

       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 is already posted.

       E_NOT_CONNECTED
            No items are connected to the menu.

PORTABILITY         top

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