NAME
     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).  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  follow-
     ing:

     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  termina-
          tion function.

     E_NOT_CONNECTED
          No items are connected to the menu.

     E_SYSTEM_ERROR
          System error occurred (see errno).

SEE ALSO

NOTES
     The header file  automatically includes  the  header
     file .

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).
