Using bind1st for a method that takes argument by reference

Question

I have a struct like this:

struct A {
    void i(int i) {}
    void s(string const &s) {}

Change references by pointers

#include 
#include 

struct A {
    void i(int i) {}
    void s(const std::string *s) {}
};


int main(void)
{
    A a;
    std::bind1st(std::mem_fun(&A::i), &a)(0);
    const std::string s("");
    std::bind1st(std::mem_fun(&A::s), &a)(&s);
}
