In python, I can use from_address:

  shape=list((c_int*rank).from_address(pi[2].contents.value))

Is there something equivalent in d? Or do I need to manually call 
ReadProcessMemory at that location?

In the c world integral types are a bit more complicated. So for 
reference take a look at the table on [0].
As long as you have a pointer to a piece of data such as int* or void* 
you should be free to dereference it to get the value.

Such as:

extern(C) int* myCFunc();

void main() {
   int value = *myCFunc();
}

that was silly - looks like I just needed to do this:

int shapex = *(cast(int*)shape);
