Re: [Boost-users] understanding placeholders

Hi, I see in the code some functions are passed things like boost::asio::placeholders::bytes_transferred. But I didn't understand what is going on, what are their aim?

Please compare with, e.g., Boost.Bind's placeholders. In this case bytes_transferred is similar to _2. Hope that helps, Kind regards, Rutger
