We don't have the user-land equivalent of the "`" kernel scoping
operator. Currently you have to find the address and then use
that in your copyin(). I'm sure you don't need any references on howto
but a previous thread can be found at:

Off the top of my head I don't know whether or not an RFE exists for
this. It sure needs to though as it gets requested quite a lot.
