/* |

* Windows implementation of the java.net.NetworkInterface native methods. |
|
39 |
* This module provides the implementations of getAll, getByName, getByIndex, |
|
40 |
* and getByAddress. |
|
41 |
* |
|
42 |
* Interfaces and addresses are enumerated using the IP helper routines |
|
43 |
* GetIfTable, GetIfAddrTable resp. These routines are available on Windows |
|
44 |
* 98, NT SP+4, 2000, and XP. They are also available on Windows 95 if |
|
45 |
* IE is upgraded to 5.x. |
|
46 |
* |
|
47 |
* Windows does not have any standard for device names so we are forced |
|
48 |
* to use our own convention which is based on the normal Unix naming |
|
49 |
* convention ("lo" for the loopback, eth0, eth1, .. for ethernet devices, |
|
50 |
* tr0, tr1, .. for token ring, and so on). This convention gives us |
|
51 |
* consistency across multiple Windows editions and also consistency with |
|
52 |
* Solaris/Linux device names. Note that we always enumerate in index |
|
53 |
* order and this ensures consistent device number across invocations. |
