Events in C++

I'm not sure how to look for this online... I think they might be called something different in C++ I want to have a simple event system, somthing like ``` event myCustomEvent; myCustomEvent.subscribe( void myHandler(string) ); myCustomEvent.fire("a custom argument"); // myHandler prints out the string passed in the first argument event myNewCustomEvent; myNewCustomEvent.subscribe( void myNewHandler(int) ); myNewCustomEvent.fire(10); // myHandler prints 10 ``` I can do this pretty easily with a simple class -- but when i want to have an event that passes a different type or amount of arguments to the subscriber i have to write, and define an entirely new event class.. I figure there has to be some library, or maybe even something native in Visual C++ 2008 that will work something similar to this. It's basicly just an implementation of the Observer pattern, so it can't be too impossible to do in C++ This really makes me appreciate how nice it is in JavaScript not to have to worry about the arguments you are passing. Tell me if this is a stupid question.
