There's is no such reversed callback mechanism for HGCM. You'd either
have to poll or make a guest thread block in a wait for directory change
HGCM call. The latter
is not that easy as an HGCM client is single threaded.

I am trying to implement directory change notification features on
windows shared folders. Basically, when files change in a host folder,
I want the host to invoke a callback function inside vm.
Thanks,
