String array from JS -> C++ via IDL

I have an IDL file and I want to add a new attribute that contains an array of strings. The interface is implemented in JavaScript and I'm writing C++ code. IDL: readonly attribute nsIArray osPaths; // DOMString[] Consuming in C++: nsCOMPtr bla; app->GetOsPaths(getter_AddRefs(bla));
