Binding with boost works while with std doesnt, whats the diffrence?

Question

I tried to bind a function with std::bind, it kept saying that there is no overload for my set of arguments. It worked with boost::bind. Whats the diffrence between std and boost bind?

Im using:

Microsoft Visual Studio Ultimate 2012 Version 11.0.60315.01 Update 2

boost 1.53.0

func declaration and bindings:

void Messenger::receiveCallback(const boost::system::error_code& error, size_t bytes_transferred, char* message, int bufferSize, tcp::socket* socketPtr, void(*onMessageReceivedCallback)(char* message, string hostname, int port, int length));

std::bind(&Messenger::receiveCallback, this, std::placeholders::_1, std::placeholders::_2, message, bufferSize, socketPtr, onMessageReceivedCallback);//error

boost::bind(&Messenger::receiveCallback, this, _1, _2, message, bufferSize, socketPtr, onMessageReceivedCallback);

errors:

105 IntelliSense: no instance of overloaded function "std::bind" matches the argument list argument types are: (void (Messenger::*)(const boost::system::error_code &error, size_t bytes_transferred, char *message, int bufferSize, boost::asio::ip::tcp::socket *socketPtr, void (*onMessageReceivedCallback)(char *message, std::string hostname, int port, int length)), Messenger *, std::_Ph<1>, std::_Ph<2>, char *, int, boost::asio::ip::tcp::socket , void ()(char *message, std::string hostname, int port, int length)) c:\Users\gospo_000\Source\Repos\Messenger\Messenger\Messenger\Messenger.cpp 176 4 Messenger

lots of errors like this one:

    if(error)
    {
        string connectionId = getConnectionId(socketPtr->remote_endpoint());
        connections_.erase(connectionId);
        cout<<error.message();
    }
    else
    {
        onMessageReceivedCallback(message, socketPtr->remote_endpoint().address().to_string(), socketPtr->remote_endpoint().port(), bytes_transferred);
        socketPtr->async_receive(
            boost::asio::buffer(message, bufferSize),
            boost::bind(&Messenger::receiveCallback, this, _1, _2, message, bufferSize, socketPtr, onMessageReceivedCallback));
    }
}

The difference is that std::bind takes only 5 arguments by default. Set _VARIADIC_MAX macro to 10 in order to increase the maximum arg number in variadic templates.
