help me with zen cart functions

Dear friends,
I want people with zen cart expertise to help me with the following zen cart functions:

1. zen_href_link(),
2. zen_image_OLD(),
3. zen_image(),
4. zen_image_submit(),
5. zen_image_button(),
6. zen_draw_form(),
7. zen_draw_input_field(),
8. zen_hide_session_id(),
9. zen_redirect();

And can anyone explain me the term "HTML wrapper function"?

I know its a lot to ask, but I don't want u people only to tell what parameters to pass in these functions and how to use them. I am not interested with the inner workings of these functions.

I have tried searching the net with no luck. The comments along with these functions are vague and can help very little. I have also looked into
catalog/includes/functions/html_output.php. The comments used along with the functions are vague. And I wanted something a little more elaborated.

So plz, plz help me.

One does not normally have to use any of these as they are already coded in the script.... If you have a specific item that you want it might be better to describe what that is than to broadly ask what you have.
