How can I pass a member function where a free function is expected?

Question

The question is the following: consider this piece of code:

#include 


class aClass
{
public:
    void aTest(int a, int b)
    {
        prin         


        

Answer 1

@Pete Becker's answer is fine but you can also do it without passing the class instance as an explicit parameter to function1 in C++ 11:

#include 
using namespace std::placeholders;

void function1(std::function fun)
{
    fun(1, 1);
}

int main (int argc, const char * argv[])
{
   ...

   aClass a;
   auto fp = std::bind(&aClass::test, a, _1, _2);
   function1(fp);

   return 0;
}
