NAME
       mitem_current - set and get current_menu_item

SYNOPSIS
       #include <menu.h>
       int set_current_item(MENU *menu, const ITEM *item);
       ITEM *current_item(const MENU *menu);
       int set_top_row(MENU *menu, int row);
       int top_row(const MENU *menu);
       int item_index(const ITEM *item);

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  when-
       ever  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
       current_item returns NULL on error.

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

       set_current_item and set_top_row return 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_BAD_STATE
	    Routine was called from an initialization or termination function.

       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.

       The SVr4 menu library documentation specifies the top_row and index_item error value as -1 (which is the value of ERR).
