Carbon and Cocoa Integration

Question

I have read the Cocoa-Carbon Integration Guide several times, but still have one unanswered question. The guide explains how to call Carbon Functions in a Cocoa Objective-C Class File. However, does this also apply to data types? I made the logical connection that it would be hard to call carbon functions without carbon data types, but i don't know if they have to be called in a special way of if a prefix needs to be added to the data types before they can be used. Could someone explain or elaborate on how to use Carbon in Cocoa Classes?
thx

Orangekay is right. You can learn it, but don't be in a hurry. If you are familiar with object-oriented Javascript, you should be able to figure it out. Cocoa is a pure object-oriented library where you send messages to receivers.
[receiver message: argument]
Carbon is also an object-oriented library, but it is written in C. In Carbon, you would do the above as:
message(receiver, argument)
Javascript looks closer to Java or C++ syntax-wise than either Cocoa or Carbon. For an example, compare the interfaces of CFString with NSString. They do the same things and are, in fact, the same objects using Carbon and Cocoa interfaces, respectively.
There are only a few objects that exist in both Carbon and Cocoa. Most things are either one or the other. Still, all Cocoa objects and methods will look similar. The same is true for Carbon.
Unfortunately, there are some low level details, like memory management, that you don't have to deal with in Javascript. You may have to step back and work on some simple C or Cocoa projects just to learn before you can apply that to something real.
