    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
           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).
