The C wrapper use this object to call the performSelectorOnMainThread: 
method on a real Objective-C object.

It depends if the call is made through an interface type or class type. 
I suggest that you write a mini-Java program that does this call (in 
Java) and then cross-compile it with --target=posix. Then you can look 
at the generated code.
