           mitem_current - set and get current_menu_item

## SYNOPSIS

           #include
           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).   cur-
           rent_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 tog-
           gled).   The  item  leftmost on the given row becomes cur-
           rent.  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 follow-
           ing:

           E_OK The routine succeeded.

           E_SYSTEM_ERROR
                System error occurred (see errno).

           E_BAD_ARGUMENT
                Routine detected an incorrect or  out-of-range  argu-
                ment.

           E_BAD_STATE
                Routine was called from an initialization or termina-
                tion function.

           E_NOT_CONNECTED
                No items are connected to the menu.

## 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).
