{ $description "\nFor the interface " { $snippet "<interface>" } ", a word " { $snippet "<interface>-iid ( -- iid )" } " is defined to push the interface GUID (IID) onto the stack. Words of the form " { $snippet "<interface>::<function>" } " are also defined to invoke each method, as well as the methods inherited from " { $snippet "<parent>" } ". A " { $snippet "<parent>" } " of " { $snippet "f" } " indicates that the interface is a root interface. (Note that COM conventions demand that all interfaces at least inherit from " { $snippet "IUnknown" } ".)\n\nExample:" }
