C++ problem (I need to get a pointer to an array of ints out of a *void)

Ok, here is my problem:
I have an int array
int previousValue[2];
Fill that up with two values and pass the adress in my call
result = (*queue)->setEventCallout (queue, QueueCallbackFunction, queue, &previousValue);
now, in my QueueCallbackFunction I get a *void refcon with the adress stored in.
How do I make a int array pointer out of that again?
My problem is that I have to store two variables (previous states of cooliehats and dpads).

int* arrayPointer = (int*)voidPointerVariable;
Then you can use arrayPointer like you would any array.
arrayPointer[0], arrayPointer[1], etc.
Perfect - as you can tell, I am not knowledgeable with pointers
