Done, it works! but I'm not sure I understand how it works... magic? :) I thought I understand why void* worked - because any pointer can be casted to void*, and real function with some pointer was replaced with wrap function with void*.
But now there is an entirely new type, which happens to have the same symbol as the old one? and they can replace each other?
