Re: [Boost-Users] Newbie boost::mem_fn problem

      Thanks Jeff. I really must spend some time getting to grips with the
boost::bind library.
Are there any sets of documentation for this? I don't find the Boost set of
docs on the topic very enlightening.

Mark.

Hello,
My problem I think is very simple, I just can't seem to find the solution
I have an STL list of object pointers and I want to call a member function
on each of the pointers in the list usigng the STL for_each algorithm.
This
would seem easy if the list contained the actual objects rather than
pointers to them, but because they are pointers I can't find a way of
doing
this.
class Block
{
public:
    void update(int x);
};
void main()
{
    list blocks;
    for_each(blocks.begin(), blocks.end(), *****);    // Call update on
each
item in list
}
what should I replace the ***** with?
Any help appreciated!
Mark.
