Enables a client to query an object proxy, or handler, for multiple interfaces by using a single RPC call. By using this interface, instead of relying on separate calls to IUnknown::QueryInterface, clients can reduce the number of RPC calls that have to cross thread, process, or machine boundaries and, therefore, the amount of time required to obtain the requested interface pointers.
The IMultiQI interface has these methods.
