int set_current_item(MENU *menu, const ITEM *item);
ITEM *current_item(const MENU *menu);

DESCRIPTION

The function set_current_item sets the current item (the item on which the menu cursor is positioned). current_item returns a pointer to the current item in the given menu.

The function set_top_row sets the top row of the menu to show the given row (the top row is initially 0, and is reset to this value whenever the O_ROWMAJOR option is toggled). The item leftmost on the given row becomes current. The function top_row returns the number of the top menu row being displayed.

The function item_index returns the (zero-origin) index of item in the menu’s item pointer list.

RETURN VALUE

top_row and item_index return ERR (the general curses error value) on error.
