Re: [Boost-users] Asio sockets - non-blocking read

You can use tcp::socket::available()
http://www.boost.org/doc/libs/1_35_0/doc/html/boost_asio/reference/basic_stream_socket/available/overload2.html

or:
boost::asio::socket_base::bytes_readable command(true);
socket.io_control(command);
std::size_t bytes_readable = command.get();
