18 * Implementation notes
19 * - Our bretheren use IOCTL_TCP_QUERY_INFORMATION_EX to get information
20 * from tcpip.sys and IOCTL_TCP_SET_INFORMATION_EX to set info (such as
21 * the route table). These ioctls mirror WsControl exactly in usage.
22 * - This iphlpapi does not rely on any reactos-only features.
23 * - This implementation is meant to be largely correct. I am not, however,
24 * paying any attention to performance. It can be done faster, and
25 * someone should definately optimize this code when speed is more of a
26 * priority than it is now.
27 *
28 * Edited implementation notes from the original -- Basically edited to add
29 * information and prune things which are not accurate about this file.
30 * Interface index fun:
31 * - Windows may rely on an index being cleared in the topmost 8 bits in some
32 * APIs; see GetFriendlyIfIndex and the mention of "backward compatible"
33 * indexes. It isn't clear which APIs might fail with non-backward-compatible
34 * indexes, but I'll keep them bits clear just in case.
35 * FIXME:
36 * - We don't support IPv6 addresses here yet -- I moved the upper edge
37 * functions into iphlpv6.c (arty)
