Passing member function with all arguments to std::function

Question

How can I create a std::function from member function without need for typing std::placeholders::_1, std::placeholders::_2, etc - I would like to \"placehold\" all arguments

Answer 1

You can easily do this with variadic generic lambdas in C++14:

template
auto smart_bind(F f, C* c)
{
  return [c, f](auto&&... args) { return (c->*f)(std::forward(args)...); };
}

// In your code:
std::function fun2 = smart_bind(&Foo::bar, &object);
