how to get a text_view with scroll bar...

[hpnadig <hpnadig lycos co uk>]

should I use:

gtk_text_view_scroll_mark_onscreen
                                            (GtkTextView *text_view,
                                             GtkTextMark *mark); ?

if so... How do I go about with the mark?
please help me..
