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).
