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
