IMultiQI interface (objidlbase.h)

  • Article

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.
