Hello all:
I have a quick question regarding boost::bind, as the subject line says.

This isn't a very viable example, but it works well enough to show what 
I want.
I have a callback I am using boost::bind to bind to, and I am passing a 
function object in as shown by the following code:
#include <cstdio>
#include <boost/bind.hpp>
#include <boost/function.hpp>

class Math
{
public:
void Add(int a, int b, int c, boost::function<void (int)> printer);
{
printer(a+b+c);
}
};

void Printer(int p)
{
printf("%d\n", p);
}How might I make this work? I am not sure how I can pass that as the 
fourth argument so that the function can be called like (1,2,3) etc. 
Also, in the actual problem I moved the function object to the first 
argument, (which just ment changing the prototype and actual function), 
but I still got errors.

Ty
