writing a simple filter for avisynth

[cypher_soundz]

Hi,
i was wondering if there are any basic tutorials and source code of simple dll's written for avisynth? preferably in C/C++ . i wouldn't mind learning about these and hopefully contribute a few good lines of code or even make my own (good) filter ;) ANY help would be appreciated to point me in the right direction.
Regards
cyph

edit: found this .cpp from a post, but seems a little confusing for me, no comments.

Well it wasnt meant to be an example of anything else but a coding style to avoid ;) This post will probably be removed since simply looking at the top post in the avisynth development forum (!) would have gotten you all the info you needed ...

But in case you read this before the moderators see your post, I got all the info I needed from simplesample :
