the concept of callable defined in http://en.cppreference.com/w/cpp/concept/callable . suppose have callable object f has 1 argument of type t* , return type void . f can callable type (a function object, pointer member function, pointer data member, etc). how can invoke f ? simply calling f(x) fails since f can pointer member function or data member. there simple way call f ? 1 possible solution std::bind(f, x)(), solution becomes more complex when f has more arguments. this std::invoke does, won't standard until c++17. can make own version, can pretty complicated if general. here's basic idea 2 cases (code taken cppreference.com): template <class f, class... args> inline auto invoke(f&& f, args&&... args) -> decltype(std::forward<f>(f)(std::forward<args>(args)...)) { return std::forward<f>(f)(std::forward<args>(args)...); } template <class base, class t, class derived> inline auto inv...
