Module Name:

|
|
|
ForceSeparateVDM.cpp
|
|
|
|
Abstract:
|
|
|
|
Force child processes to use a separate VDM.
|
|
|
|
This can be useful if the parent process wants to wait on a handle returned
|
|
by CreateProcess. This only works because of a hack in the VDM that returns
|
|
and actual thread handle that will go away along with the process if a VDM
|
|
doesn't already exist.
|
|
|
|
Notes:
|
|
|
|
This is a general purpose shim.
