[Boost-users] [boost::function] Is there a way to assign a generic function, regardless number of parameters?

Hello list, My doubt is simple. We need to implement some callbacks, but we don't want to declare a boost::function to every different callback, we just want to declare one generic boost::function to receive any function, with any number of parameters (the return type may be one well defined, no problem with that in our case). Is there a way to do this? What we want to do is something like is done in the asynchronous methods of boost::asio when passing the callback to the async operation.
