Confused about referencing in D

[Gorge Jingale via Digitalmars-d-learn]

I'm pretty confused why the following code doesn't work as 
expected.

GetValue is a struct.

   auto value = GetValue();
   memcpy(&value, &val, Val.sizeof);

But if I plug in value direct to memset it works!!

   memcpy(&GetValue(), &val, Val.sizeof);

GetValue returns memory to stick a value in and the memcpy is 
copying it over. It is very confusing logic. Should I not expect 
the two cases two be identical?

I think that the assignment in the first case is not assigning 
the reference returned by auto ref GetValue().

I am expecting it to work like a pointer,

   void* value = &GetValue();
   memcpy(value, &val, Val.sizeof);

so to speak but it works more like

     S value;
     value = GetValue();
     memcpy(&value, &val, Val.sizeof);

which copies the data to the memory created for value and not the 
one returned by GetValue.
