 // Summary:
 //   creates a socket for listening, and bind()s and listen()s it.
 // Args:
 //   host - hostname or numeric address, or empty-string if you want
 //          to bind to listen on all addresses
 //   port - a port number or service name. By service name I mean a
 //          -real- service name, not a Google service name. I'd suggest
 //          you just stick to a numeric representation like "80"
 //   is_numeric_host_address -
 //           if you know that the host address has already been looked-up,
 //           and will be provided in numeric form like "130.207.244.244",
 //           then you can set this to true, and it will save you the time
 //           of a DNS lookup.
 //   backlog - passed into listen. This is the number of pending incoming
 //             connections a socket which is listening may have acquired before
 //             the OS starts rejecting new incoming connections.
 //   reuseaddr - if true sets SO_REUSEADDR on the listening socket
 //   reuseport - if true sets SO_REUSEPORT on the listening socket
-//   wait_for_iface - A boolean indicating that CreateListeningSocket should
+//   wait_for_iface - A boolean indicating that CreateTCPServerSocket should
 //                    block until the interface that it will bind to has been
 //                    raised. This is intended for HA environments.
 //   disable_nagle - if true sets TCP_NODELAY on the listening socket.
 //   listen_fd - this will be assigned a positive value if the socket is
 //               successfully created, else it will be assigned -1.
