I don't know what a classic Atom is either, but it seems like you may
be missing the fact that "classic" may refer to the traditional Mac
API's prior to the introduction of Carbon. Searching OLD Apple
documentation might help. I could be wrong.
Regarding nib files:
Apple is quite clear (and so are several third party references) that
Cocoa nib files are just Objective-C objects archived into a file.
This is similar to Java serialization... Cocoa provides several ways
of archiving ranging from compact binary to wordy keyed archiving XML.
You are free to look at the XML files yourself. The only non-obvious
thing about nib files is that some of the archived objects are
particular to Interface Builder and defined in
InterfaceBuilder.framework such as IBConnector.
I have no idea what Carbon nibs are all about.

Greetings,
This is probably best handled for QT List, but I subscribe to enough
lists...perhaps someone can point me in a quick directions.
I was reading information on Quicktime file formats and in the
introduction of explaining QT Atoms, it compares them to "classic
atoms". Okay, so to understand QT Atoms, you need to know about
classic atoms fine. So I didn't get a degree in CS but and familiar
with data structures and such and never came across an atom. I have
heard of trees and leafs and nodes, by no subatomic structures (that
was physics).
I did a search on the web and only come up with Apple references, I
check the half dozen C books and no atoms, I even went and polled a
few java and C++ books. No Atoms or classic atoms.
Seeing that Apple loves to do this all the time.....explaining one
thing with another.....and never explaining the later (what the hell
is a nib really? in concrete terms aka show me the dam thing) Does
anyone in less than two paragraphs or less point me to or explain
exactly what a classic atom is. What is the structure definition,
things you do with it ect.
The reason I ask for classic atoms is that Apple literature states
that some QT Atoms are just classic atoms and others are not. Since a
classic atom is never defined, How is one to compare.
(Sorry I vent but Apple might once and a while might ask why there are
not as many Mac developers, and it is times like this I understand
why. Mind you I went and bought the Inside QT File format from apple
and the first page starts off with defining QT Atoms as similiar to
classic atoms ..... well since that is their defination, then I
better well know what a classic atoms is....but can't find any
reference to what it is!!!!)
Any help would be greatly appreciated.
Jim
