I have an interface with a method that takes an [in, out, unique] int*

interface IVendor : IUnknown
{
HRESULT ReturnInteger([in, out, unique] int *);
};

but when i compile the project and get the type library i dont find
the "unique" attribute described in the method description in the type
library.

Type library format is not full fidelity: only a subset of features
available in IDL is preserved in TLB. Baically, just enough to make
automation work.

I need to programmatically find out from the typelibrary if a pointer
parameter is tagged unique so i could modify the marshalling code in
my Java-DCOM implementation.

I'm afraid you are sadly out of luck. You'll probably have to parse IDL
directly.

With sufficient thrust, pigs fly just fine. However, this is not
necessarily a good idea. It is hard to be sure where they are going to
land, and it could be dangerous sitting under them as they fly
overhead. -- RFC 1925
