| * {@code gethostname()} function from {@code Ws2_32} library. |
| * (without domain name). Note that this Windows function will do a |
| * name service lookup and the method is therefore potentially blocking, |
| * although it is more than likely that Windows has cached this result |
| * on computer startup in its DNS Client Cache and therefore the |
| * result will be returned very fast.</li> |
