/* client side: we only care about the [in] part.
|
||
|
|
it's basically like unmarshal on the server side, just that
|
||
|
|
we immediately free the buffer (virtual stack) after unmarshalling.
|
||
|
|
The call it not necessary always OLE call: one side raw RPC and
|
||
|
|
the other side OLE call is possible: do we support this?
|
||
|
|
|
||
|
|
mostly code from NdrStubCall2, remove irrelavant code.
