Re: [Boost-users] How to get the port number and the address of a boost::asio::ip::tcp:acceptor object

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?

Try this: boost:;asio::ip:tcp:;acceptor acceptor(m_IOService); acceptor.listen(); boost::asio::ip::tcp::endpoint endpoint = acceptor.local_endpoint(); I pulled this from code I have that works. You probably forgot to call listen() first. -- Jon Biggar Floorboard Software jon@floorboard.com jon@biggar.org
