Hi,

thanks for the quick answer. By port number and ip address of an
acceptor" I mean the address and the port of the ip interface the
acceptor is listening on.
In most of the case I've worked on, I used the specify the port I
wanted to listen on, though for this special case, I do not want the
acceptor to specify a port number.

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"

I need to know the ip address and the port number fo the acceptor
before calling the accept method.

Any thoughts?

Thanks
