IRpcProxyBuffer Interface
IRpcProxyBuffer interface is the interface by which the client-side infrastructure (for example, the proxy manager) talks to the interface proxy instances that it manages. When created, proxies are aggregated into some larger object as per the normal creation process (where pUnkOuter in IPSFactoryBuffer::CreateProxy() is non-NULL). The controlling unknown will then QueryInterface() to the interface that it wishes to expose from the interface proxy.
interface IRpcProxyBuffer : IUnknown {
virtual HRESULT Connect(pRpcChannelBuffer) = 0;
virtual void Disconnect() = 0;
};
