Subject: Use of XEN_GUEST_HANDLE

Hi all,
   I have recently started to go through xen source. I want to know the
usage of XEN_GUEST_HANDLE.
 I see thats its just a macro which will prefix each data type with
__guest_handle_ . And DEFINE_XEN_GUEST_HANDLE(name) will just typedefs
'__guest_handle_name' to be a pointer to a data type 'name ' .

What is the reason for such abstraction?  

And how this XEN_GUEST_HANDLE different from 'guest_xc' field of 'struct
xc_dom_image', which gets initialized with xc_handle.
 
I have serached the net extensively for answers, but unable to get any. So
any info or pointers would be highly appriciated.

Thanks 
 -Sandesh
