My main purpose is to have a generic data buffer that I can use for transfers.
I'm thinking of something along the lines of what XCopy did.
Is there something already made out there or a good example one can follow?

A:
The Tomes of Delphi by Julian Bucknall describes code for circular buffers, the code of which is freely available as a download. I haven't got the book to hand at the moment, so I can't tell you exactly where to look (though I think it might have had something to do with carrying out data compression with a sliding window).

The sources that you mean can be downloaded here: http://www.boyet.com/Code/ToDADS_source.zip. It looks like you can get the book for $28 here: http://www.lulu.com/content/435417

I should add that the book is worth every cent/penny.

This is not meant to be a JFGI-response, but I usually find Google CodeSearch very useful when I'm looking for code examples:
http://www.google.com/codesearch?as_q=circular+buffer&as_lang=pascal
It came up with the following:
- Circular.pas (OO TP7 code; should be easy to adapt)
- CircularBuffer.pas (FPC code?)
- Buffer.pas (OO TP code)
- Bfg.Containers.CircularBuffer.pas (jedi)
A search through my lib folder came up with the following:
- TurboPower AsyncPro has a circular buffer in AxTerm.pas
- unitStreamTextReader.pas from Colin Wilson's Delphi Components for Delphi 2009 has a circular buffer class

+1 for the "teach a man to fish" metaphor analogy instead of just turning the results over.

@Wouter: you just gave me a DUH moment... I use Google Search all the time for trivial and non trivial stuff, why the heck didn't I use Google Code to search for stuff, ARGHHHH. Well thanks anywho...
