Re: [Boost-users] udp::endpoint listen_endpoint invalid argument

Quoting the documentation: "from_string Create an address from an IPv4 address string in dotted decimal form, or from an IPv6 address in hexadecimal notation." You need to resolve "localhost" first.
Thanks Bjorn and Gavin, change localhost to an IPv4 address fixed that problem, so how can we use the domain name rather than the IPv4 dot address? Cheers. On Tue, Apr 11, 2017 at 7:21 PM, Bjorn Reese via Boost-users < boost-users@lists.boost.org> wrote:

As Bjorn suggested, you need to call resolve or async_resolve on a tcp::resolver or udp::resolver. There are other examples that demonstrate this.
