I have a signal boost::signal foo that I would like to pass to a function taking a function. Currently, I pass the pointer to a helper function that calls foo(), but I suspect there's an easier way.

Same goes for the more advanced case, where i have a signal boost::signal foo which i would like to the same function (taking a function), after binding the signal parameter to a specific value. Does anyone know how to do this as well?

You could define the function as a template that takes "callable" parameter, then pass either boost::function or boost::signal (or a binder with that signal). template<typename Callable> func(Callable callable) { callable(); }
