Hello,
I've seen an issue when using getifaddrs() using Cygwin 1.7.x (snapshot
build from 2010-11-24, shortly after the ARP fixes from Corinna).
Operating System is Windows 7 x64_86 Ultimate.
When I use getifaddrs() I get a list of interface names, some are
appended with ":1".
Getting the list with ioctl(SIOCGIFCONF) provides a different list of
names, where interface names only differ sometimes by ":1".
The list from ioctl() is correct, that from getifaddrs() is incorrect,
in that the name cannot be used to resolve the HWADDR, SIOCGIFFRNDLYNAM
with ioctl().
Using getifaddrs():
device: {4ED54D4E-1024-4BDF-A926-67D2895D2DC4};
ioctl(SIOCGIFFRNDLYNAM)=0 Local Area Connection 4
