mitem_current(3)                                 mitem_current(3)


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).   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.

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).
