* Adapted API as needed, and implemented most of the C++ API - it's completely
untested at this point, though. * Will port ifconfig, NetworkStatus, and the Network preferences application later in order to test the API. git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@37988 a95241bf-73f2-0310-859d-f6bbb57e9c96
