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

Hi,

I built doc/html/boost_asio/example/timeouts/blocking_udp_client.cpp on
Debian Jessie, but when I run it, I got Invalid argument on the statement
of udp::endpoint listen_endpoint(
boost::asio::ip::address::from_string(argv[1]), std::atoi(argv[2]));

To simplify it, I changed to:
udp::endpoint listen_endpoint(
boost::asio::ip::address::from_string("localhost"), 15555);

Appreciate any clues what's wrong with that statement and why it caused
invalid argument?

Thank you.
