It is specified in http://www.boost.org/doc/libs/1_47_0/doc/html/boost_asio/reference/AcceptHan... that a handler for `async_accept()` must satisfy the following function signature:
void accept_handler( const boost::system::error_code& ec) { ... }
However, in the `Daytime.3` example, using boost::bind, the handler can be specified as much parameter as desired, as long as it does not exceed the limit of `boost::bind` (which is 9 arguments at maximum): <...> Why is that possible? I thought even with `boost::bind`, the exact function signature still has to be matched.
It is possible, because bind creates a functor that exposes operator() having the number of arguments that matches the expectations of the completion handler caller.
