Subject: Calling class methods from C

Hello,

I'm trying to call a class method from C. I've tried all combinations of
rb_intern I could think of to make it work, but I've gotten nothing.

Example class

class CallTest
def go
(do something here)
end

end

rb_funcall(?, rb_intern("go"), 0);

What goes in the ? space? I know if I use Qnil there, it will call
global functions, but I'd prefer class methods.

Am I heading in the wrong direction?

Also, I'd prefer not to have to know the class name ahead of time if
possible, but if I have to require that I know what it is, I can try
passing it by name to my application.

I'm using SWIG to generate the binding.
