[Boost-users] [LAMBDA] calling a function pointer stored in a struct

Hi

I'm new to the boost::lambda lib, and have a problem.
I have a list that stores struct objects. One field of the struct is a 
function pointer. I'd like to call the function pointer stored in each 
element of the list, but I can't get it right.
First, I tried something like this:

struct S
{
        typedef void (*Func)();
        Func f;
        ...
};
...
std::list<S> l;
...
for_each(l.begin(), l.end(), bind(&S::f, _1));

I think this doesn't work because the bind yields a function object that 
returns f itself, but doesn't call it. Instead, I'd need to build a 
function object that returns the result of calling the f stored in the 
current list node. Unfortunately, I don't know how to do it.
Thanks for any help.
