[lug] Passing member functions around

[Chris Riddoch]

I realize there are probably better forums for this, but I know a
number of people on the BLUG use C++ on a regular basis, and I hope
someone can help me out.

The question: what's the syntax for passing a member function to
another member function?  My project is vaguely like the example
below, but has about half a dozen functions that will need to be
passed to the iterator from about twelve others, and it's all
implemented over a linked list, so the iterator is actually useful in
my real program.

Compilation breaks on the call to iterator() in do_body() because I
can't figure out the syntax for sending body() to iterator().

Thanks.

#include <iostream>

int times=20;

class thing {
public:
  
  int body(int number)
  { cout << number << endl; return 0; }

  void iterator(int times, int (*inner)(int number))
  {
    for (int i = 0; i < times; i++)
      inner(i);
  }

  void do_body()
  {
    iterator(10, body); // How do I pass 'body' to iterator?
  }

};

int main()
{
  thing a;
  a.do_body();
}
