typedef ComponentResult(* TweenerDataProcPtr) (
    TweenRecord *tr, 
    void *tweenData, 
    SInt32 tweenDataSize,

You would declare your function like this if you were to name it MyTweenerDataCallback:

ComponentResult MyTweenerDataCallback (
    TweenRecord *tr, 
    void *tweenData, 
    SInt32 tweenDataSize, 
    SInt32 dataDescriptionSeed, 
    Handle dataDescription, 
    ICMCompletionProcRecordPtr asyncCompletionProc, 
    UniversalProcPtr transferProc, 
    void *refCon
);
