It's idiomatic to push as much as possible to JS land. Here is a minimal C++ event emitter and a JS shim that does the actual dispatching. Dispatching is left as exercise to the reader. :-) // in Init() Persistent<Object> context_obj = Persistent<Object>::New(Object::New()); target->Set(String::New("context"), context_obj); // elsewhere in your code Local<Value> args[] = { String::New("ping") }; node::MakeCallback(context_obj, "on", ARRAY_SIZE(args), args); And the JS shim: var bindings = require('./bindings'); // the .node file bindings.context.on = function(name) { console.log(name); // prints "ping" // now invoke the user's callbacks }; Hope that helps. -- Job Board: http://jobs.nodejs.org/ Posting guidelines: https://github.com/joyent/node/wiki/Mailing-List-Posting-Guidelines You received this message because you are subscribed to the Google Groups "nodejs" group.
