C++ Function Callbacks: Cannot convert from a member function to a function signature

Question

I\'m using a 3rd party library that allows me to register callbacks for certain events. The register function looks something like this. It uses the Callback signature.

Answer 1

class ICallBackInterface
{
public:
    virtual void FireCallBack( std::string& str ) = 0;
};

std::set CallBackMgr;

class MyStruct : public ICallBackInterface
{
public:
    MyStruct()
    {
        CallBackMgr.insert( this );
    }

    ~MyStruct()
    {
        CallBackMgr.erase( this );
    }

    virtual void FireCallBack( std::string& str )
    {
        std::cout << "MyStruct  called\n";
    }
};

void FireAllCallBack(std::string& str )
{
    for ( std::set::iterator iter = CallBackMgr.begin();
        iter != CallBackMgr.end();
        ++iter)
    {
        (*iter)->FireCallBack( str );
    }
}

This is another way to use polymorphism to achieve the same effect
