Hi,

you probably misunderstood IOChannels. You have to create a socket
first, then bind/accept/whatever and then create IOChannel with
create_from_fd static method (or else). GIOChannels were created
probably for portable I/O operations like reading from and writing to,
since these are most often use cases of files/sockets/pipes. But
creating them was meant to be written in some sort of backend code like
this:

Glib::RefPtr<Glib::IOChannel> get_channel()
{
#ifdef WINDOWS
  // create a socket in windows and obtain its descriptor
  int s_fd = something();
  Glib::RefPtr<Glib::IOChannel> my_channel =
Glib::IOChannel::create_from_win32_socket(s_fd);
#else
  int s_fd = socket(...);
  Glib::RefPtr<Glib::IOChannel> my_channel =
Glib::IOChannel::create_from_fd(s_fd);
#endif
  return my_channel;
}

For sockets - use GSocket. But C++ wrapper of GSocket just hit the
unstable version of Giomm, so you'll probably have to use C API.
