Michael,
Thanks. This is the info I needed.
I was trying not to modify the main line code. If there is no better way, I
guess need to modify the host call to pass the vm info I needed.
By the way, we have added copy/paste of files between guest and host, so a user
can do Control-C/Control-V for file copying, etc. To do this, we added CF_HDROP
format support to the shared clipboard. We used our own shared folder
additions. if you would like to add this support to the main line of code, pls
let me know. (we only did it on windows guest and host).
We may add drag-drop support on windows later on

HGCM services have no built-in mechanism for getting information about
the VM they are running in and such-like. This is because they were
originally designed to work in things like VBoxBFE, which is a
simplified frontend where the normal VirtualBox APIs are not available.
What you can do instead is to use the HGCM "host call" functionality to
pass any needed information into the service when it is started. To see
examples of this, grep for "HostCall" in src/VBox/Main/ConsoleImpl[2].cpp.
If you need to get information or send notifications or whatever while
the service is running, you can also register callbacks ("host service
extensions") with the service. For an example of this, grep for
"ServiceExtension" in ConsoleImpl2.cpp.
BTW, I haven't forgotten the VbglR3GuestPropWait() issue you mentioned,
but I haven't got round to looking at it yet. Sorry!
Regards,
Michael
