GetItem, get_Item, Release and NULL

In C++ COM if I use GetItem do I have to Release the pointer returned to me?

 

Or set it to NULL

 

Or do nothing because it is already handled properly?

 

And how does that compare when I use the other format, get_Item ?

 

I realise that GetItem can throw an exception whereas get_Item returns an error value, but beyond that do I treat the pointers in the same way?
