Hi guillaume.
Thanks for your comments.
I only used babelfish.altavista.com to translate your question and the translation is very poor... (I could not speak french, sorry)

If i understand it on the right way, you want to get the DLL Informations to create your own DLL. Right?
So - on what system do you want to create it? Maybe we could talk about that, so you could write the DLL for that system. But - please write directly to joel, he is the person knowing all about the DLL's...
In the moment he had to work hard, so it may take some days to get an answer...

Kind Regards,
Daniel
