mitem_current(3X)		 Library calls		     mitem_current(3X)

NAME
       mitem_current - set and get current_menu_item

SYNOPSIS
       #include	<menu.h>

       int set_current_item(MENU *menu,	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 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
       current_item  returns  a	 pointer (which	may be NULL).  It does not set
       errno.

       top_row and item_index return ERR (the general curses error  value)  if
       their menu parameter is NULL.

       set_current_item	and set_top_row	return one of the following:

       E_OK The	routine	succeeded.

       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.

       E_SYSTEM_ERROR
	    System error occurred (see errno(3)).

PORTABILITY
       These  routines	emulate	the System V menu library.  They were not sup-
       ported on Version 7 or BSD versions.

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