What is the practical use of pointers to member functions? http://stackoverflow.com/questions/3957348/what-is-the-practical-use-of-pointers-to-member-functions to one or a stack reference and call it so instance. mem_func_ptr .. or instance mem_func_ptr .. My question is based on this.. and call it so instance. mem_func_ptr .. or instance mem_func_ptr .. My question is based on this since you have the instance.. why not call the member function directly like so instance.mem_func .. or instance mem_func .. What is the rational practical use..
