Re: [Boost-users] bind for_each and a range of functors

Let's say I have a std::list of a functor with a member function

virtual operator()( int, int )

Is there an easy way to call each function in this list using for_each?

Intuitively I'd expect to be able to do something like:

void call_each( std::list<functor>& l ) { std::for_each( l.begin(), l.end(), boost::bind(_1,5,20) ); }

With boost::bind, which doesn't evaluate its first argument, you'll need to use apply<>, as explained in

Ah I knew it would be obvious. Missed that thanks! -- Michael Marcin
