[asio-users] How to use ip::v6_only with tcp::acceptor?

[Asbjørn <lo...@gm...>]

Hi,

I'm fairly new to asio and I tried to modify some server code to handle 
ipv6 as well. The code should run on win/linux/osx and thus the easiest 
way seems to be to enable the v6_flag and launch two listening threads, 
one for ipv4 and one for ipv6.

I'm having some difficulty understanding how to enable the v6_only flag 
with tcp:acceptor, which the current code uses. I tried setting it on 
the acceptor but that failed.

If there is alternative to the acceptor that is ok, the main feature I 
need is to be able to use a stream, and accept connections in a loop as 
shown below (server can only handle one client at a time).

I'm using asio from Boost 1.43.

My listening thread code looks like this:

boost::asio::io_service io_service;
tcp::endpoint endpoint(ipversion == 4 ? tcp::v4() : tcp::v6(), listenPort);
tcp::acceptor acceptor(io_service, endpoint);

while (server->signal == SIG_NONE) {
	tcp::iostream stream;
	acceptor.accept(*stream.rdbuf());

	... process request using stream
}

Any help is much appreciated.

Cheers
