here is one of the example, maybe not the best.

#include <vector>
#include "boost/function.hpp"
#include "boost/bind.hpp"

void apply( boost::function<void(int)> f, int i)
{
    f(i);
}

int main( )
{
    static boost::function<void(int)> my_function = 0;

    std::vector<int> v;

    std::for_each(v.begin(), v.end(), boost::bind(apply, my_function, _1));
}
