How to use std::async on a member function?

by

Something like this:

auto f = std::async(&Person::sum, &p, xxx);

or

auto f = std::async(std::launch::async, &Person::sum, &p, xxx);

where p is a Person instance and xxx is an int.

This simple demo works with GCC 4.6.3:

#include <future>
#include <iostream>

struct Foo
{
  Foo() : data(0) {}
  void sum(int i) { data +=i;}
  int data;
};

int main()
{
  Foo foo;
  auto f = std::async(&Foo::sum, &foo, 42);
  f.get();
  std::cout << foo.data << "\n";
}
