Functions don't have access to any instance methods (how could they, they don't have an instance). Typically, what one would do is pass 'self' as the info parameter, and then either access instance variables through info (by casting it to a pointer to your class type), or simply call a method on that same instance, and do your work there. -- Clark S.
