Hi, One of the really nice features of c++ IMHO are iostreams. Just define the << operator and voila, you can outut you object to the console or files etc. The problem is what if I wanted to replace cout in the first place? What if I wanted to do say, coutGL << "Lalalala" << endlGL; to output to an OpenGL scene, how could that be accomplished? This is not a GL question... I''m interested in overloading?/ inhereting from? cout. Thanks, OberonZ ---

Im not sure about the overloading inheriting part of cout, but you could try this. Just make a class that has your output routines and contains an operaotor overload of << and has what you want to do with it through the function implementation.

class foo
{
private:
...
public:
friend ostream& operator<<(whatever params you need)
};

Then code the function body in the .cpp file for your class. Since it is a friend function, when you add the body omit the foo:: part of it. The just instantiate an object of your class and when ever you use the << on a member of that class your overloaded << will get called.
