Hi, The following code: boost::asio::ip::tcp::acceptor myacceptor(m_IoService); myacceptor.open(boost::asio::ip::tcp::v4()); boost::asio::ip::tcp::endpoint endpoint = myacceptor.local_endpoint(); generates the following exception: "An invalid argument was supplied" when myacceptor.local_endpoint() is invoked. any idea?

Then when I do:

boost::asio::ip::tcp::acceptor acceptor(m_IoService);

when I call

boost::asio::ip::tcp::endpoint endpoint = acceptor.local_endpoint();

I get an exception as follow: "The file handle supplied is not valid"

You have to open() the acceptor: http://www.boost.org/doc/libs/1_35_0/doc/html/boost_asio/reference/basic_soc...
