Ummm. Because it is not defined as having one? Did you even LOOK at the definition of the structure? And then wonder why it's not there?

You might want to ask these questions on the CoreAudio mailing list. This is basic programming, not something related to Xcode.
In fact, had you spend *5 seconds* to google for "transportStateProc" you would have found the FIRST hit:

The answer to your problem is trivial, but I'll let you find it from the above CoreAudio link
