Newbie boost::bind problem

Hello,
I need some help using the boost::bind library. I have a map of objects 
with a string as the key eg map<string, Block*>, what I want to do is 
call a member function on each Block* in the map using the std::for_each 
algorithm. The trivial solution would be to craft my own loop and 
iterate through the list calling the member function on each one. But 
I'm sure that the boost::bind library can help me out there.

class Block
{
public:
     void update(int x);
};

void main()
{
     map<string, Block*> blocks;
     for_each(blocks.begin(), blocks.end(), *****);
}

what should I replace the ***** with to call update() on each block?

Any help appreciated!

Mark.
