wp_get_attachment_link() with text only

Hi

I’m trying to use wp_get_attachment_link() to return a hyperlink only to the attachment. I don’t want a thumbnail. Even though the codex here:

http://codex.ww.wp.xz.cn/Template_Tags/wp_get_attachment_link

says in option 3 you can have text only, I don’t understand how to add a parameter accordingly. The default option seems to be to display a thumbnail.

Thanks
