may COM server reallocate ([in, out] CACLSID * arg) ?
With a COM interface method declared as this:


    [ object,
      uuid(....),
    ]
    interface IFoo : IUnknown 
    {
      HRESULT Foo([in, out] CACLSID * items);
    }

With regards to marshalling, is the server allowed to reallocate the counted array? (I *think* it is, but I am not sure anymore)

Its current implementation only replaces the existing ID's, but I'd like to implement a change (that would not break contract) that may return more items without introducing a new interface.
