Abstract
A computer method and system for passing a pointer to an interface from a server process to a client process. In a preferred embodiment, the server process instantiates an object that has multiple interfaces. The server process identifies an interface to pass to the client process and creates a stub object for receiving a request to invoke a function member of the interface and for invoking the requested function member upon receiving the request. The server process then sends an identifier of the stub to the client process. When the client process receives the identifier of the stub, it instantiates a proxy object for receiving requests to invoke a function member of the interface and for sending the request to the identified stub. The client process can then invoke the function members of the interface by invoking function members of the proxy object. The proxy object sends a request to the identified stub. The identified stub then invokes the corresponding function member of the interface.
