Hello. I am trying to write a simple server, and I am using an
asynchronous acceptor to get clients:
  acceptor.async_accept(crtclient->getSocket(),
boost::bind(&Server::gotClient, this, boost::asio::placeholders::error));
As soon as this is executed, my Server::gotClient gets called with
ec.message()="An invalid argument was supplied."
<...>
What could be wrong? Am I constructing socket incorrectly with
socket_(ioserv)? Because if I construct it with socket_(ioserv,
boost::asio::ip::tcp::v4()), I get the error "Already open" in
ec.message(), rather than "An invalid argument was supplied".
