C++ delegate creation with boost

Question

I asked a similar question here C++ delegate creation but I need to do this with a new restriction. I'll quickly restate the question

I was wondering if theres a way to mimic this delegate behaviour (from C#) in C++

new ModifyTargetingStatus("Reversal", "Reverses physical attacks back at the user", -1, new List<CALL_CONDITION>(){CALL_CONDITION.Targetted}, attemptChange: delegate(CharacterMove move, BattleCharacter[] users, ref BattleCharacter[] targets, BattleCharacter holder, BattleField field)
                {
                    if (targets != null && targets.Length == 1 && targets[0] == holder &&
                        (move.MoveClass == MOVE_CLASS.MC_BASIC_ATTACK ||
                        move.MoveClass == MOVE_CLASS.MC_STACKED_ATTACK) &&
                        !move.MoveFlags.Contains(MOVE_FLAG.MF_UNREFLECTABLE))
                    {
                        targets = users;
                        move.Reflected = true;
                        return true;
                    }
                    return false;
                })

I need to be able to do this without using C++0x as I'm stuck on a version of gcc the doesnt support C++0x lambdas. I have the boost library available but I'm jut getting into it so I can't figure out how to do this specifically.

Thanks in advance for the help

Either library should work for creating unnamed functions.

See this question too, note that the two libraries will be merged some day.

boost::bind is the usual solution to this problem. Refer to their documentation for details.
