[Xen-devel] XEN_GUEST_HANDLEs - help

[beth kon <eak@xxxxxxxxxx>]

Hi. I am playing with some code and not sure how to do what I want to do.

In the physinfo struct:
XEN_GUEST_HANDLE_64(uint32_t) cpu_to_node;

So if I am in tools/libxc/xc_misc.c

and want to do (effectively)
xc_physinfo_t *put_info
....
put_info->cpu_to_node[0] = NUMA_NO_NODE;

how can I access the contents of the XEN_GUEST_HANDLE from the tools 
side? Can anyone explain how these XEN_GUEST_HANDLEs work? I am not 
quite getting what I see in the code
