Example #1

int MC_protocol_hello(int socket)
{
  int e;
  if ((e = MC_protocol_send_simple_message(socket, MC_MESSAGE_HELLO)) != 0) {
    XBT_ERROR("Could not send HELLO message");
    return 1;
  }

      continue;
    else {
      XBT_ERROR("Could not receive HELLO message");
      return 2;
    }
  }
  if ((size_t) s < sizeof(message) || message.type != MC_MESSAGE_HELLO) {
    XBT_ERROR("Did not receive suitable HELLO message. Who are you?");
    return 3;
  }
