std::bind

#include <functional>

using namespace std::placeholders;

class Class
{
public:
	Class(const std::string& name)
		: m_name(name)
	{}

	int member(int intArg, float floatArg)
	{
		std::cout << "I am a non-static member of " << m_name << ": "
			<< intArg << ", " << floatArg << "." << std::endl;

	}

private:
	std::string m_name;
};

static int nonMember(Class* who, int intArg, float floatArg)
{
	std::cout << "I am a static wrapper." << std::endl;
	return who->member(intArg, floatArg);
}

static int doSomething(std::function<int(int, float)> f, int intArg, float floatArg)
{
	return f(intArg, floatArg);
}

int main(int argc, char** argv)
{
	Class c("misiu");
	Class d("czuterek");

	return doSomething(std::bind(nonMember, &c, _1, _2), 1, 2.3f)
		+ doSomething(std::bind(nonMember, &d, _1, _2), 4, 5.6f);
}

produces the following output:

I am a static wrapper.
I am a non-static member of misiu: 1, 2.3.
I am a static wrapper.
I am a non-static member of czuterek: 4, 5.6.
