[Boost-users] intrusive list with pointer_plus_bit

Hi,

I have a class X : public intrusive::list_base_hook<> and would like
to embed an additional member bool using the pointer_plus_bit.

Can this be achieved using the value_traits somehow, and have the list
working 'appropriately'?

example code:

#include <boost/function/function0.hpp>
#include <boost/intrusive/list.hpp>
#include <boost/intrusive/pointer_plus_bit.hpp>

struct X : public boost::intrusive::list_base_hook<>
{
        template<typename F>
        X(F const& f) : f_(f) {}
        boost::function0<void> f_;
};

void foo() {}

void test_intrusive()
{
        typedef boost::intrusive::list<X> ilist;
        ilist list;
        list.push_back(*(new X(&foo)));
        X& x = list.back();
        // How to set/get the bit on x?

};

Thanks,
Christian
