我在windows NT 2000 Native API reference 上查到了这个函数，
但是说明太简单了：
ZwVdmControl performs a control operation on a VDM.
ZwVdmControl(
IN ULONG ControlCode,
IN PVOID ControlData
);
Parameters
ControlCode
The control code for operation to be performed.
ControlData
Pointer to a caller-allocated buffer or variable that contains the data required to
perform the operation.
