Re: [Boost-users] [boost] [asio] how to handle "boost::asio::placeholders::error" in "boost::function"?

     //compile error because of the placeholder      boost::function fun = boost::bind(&transfor_file_push::write_file, this, boost::asio::placeholders::error, conn);

The signature of the resulting functor is not void(void), it's void(const boost::system::error_code &)
