Revision 1.23  2005/10/05 20:55:14  herscher
<rdar://problem/4096464> Don't call SetLLRoute on loopback interface

Revision 1.22  2005/03/04 22:44:53  shersche
<rdar://problem/4022802> mDNSResponder did not notice changes to DNS server config

Revision 1.21  2005/03/03 02:29:00  shersche
Use the RegNames.h header file for registry key names

Revision 1.20  2005/01/25 08:12:52  shersche
<rdar://problem/3947417> Enable Unicast and add Dynamic DNS support.
Bug #: 3947417

Revision 1.19  2004/12/15 07:34:45  shersche
Add platform support for IPv4 and IPv6 unicast sockets

Revision 1.18  2004/10/11 21:53:15  shersche
<rdar://problem/3832450> Change GetWindowsVersionString link scoping from static to non-static so that it can be accessed from other compilation units. The information returned in this function will be used to determine what service dependencies to use when calling CreateService().
Bug #: 3832450

Revision 1.17  2004/09/17 01:08:57  cheshire
Renamed mDNSClientAPI.h to mDNSEmbeddedAPI.h
  The name "mDNSClientAPI.h" is misleading to new developers looking at this code. The interfaces
  declared in that file are ONLY appropriate to single-address-space embedded applications.
  For clients on general-purpose computers, the interfaces defined in dns_sd.h should be used.

Revision 1.16  2004/08/05 05:43:01  shersche
<rdar://problem/3751566> Add HostDescriptionChangedCallback so callers can choose to handle it when mDNSWin32 core detects that the computer description string has changed
Bug #: 3751566

Revision 1.15  2004/07/26 05:42:50  shersche
use "Computer Description" for nicename if available, track dynamic changes to "Computer Description"

Revision 1.14  2004/07/13 21:24:25  rpantos
Fix for <rdar://problem/3701120>.

Revision 1.13  2004/06/24 15:23:24  shersche
Add InterfaceListChanged callback.  This callback is used in Service.c to add link local routes to the routing table
Submitted by: herscher

Revision 1.12  2004/06/18 05:22:16  rpantos
Integrate Scott's changes

Revision 1.11  2004/01/30 02:44:32  bradley
Added support for IPv6 (v4 & v6, v4-only, v6-only, AAAA over v4, etc.). Added support for DNS-SD
InterfaceID<->Interface Index mappings. Added support for loopback usage when no other interfaces
are available. Updated unlock signaling to no longer require timenow - NextScheduledTime to be >= 0
(it no longer is). Added unicast-capable detection to avoid using unicast when there is other mDNS
software running on the same machine. Removed unneeded sock_XtoY routines. Added support for
reporting HINFO records with the  Windows and mDNSResponder version information.

Revision 1.10  2003/10/24 23:23:02  bradley
Removed legacy port 53 support as it is no longer needed.

Revision 1.9  2003/08/20 06:21:25  bradley
Updated to latest internal version of the mDNSWindows platform layer: Added support
for Windows CE/PocketPC 2003; re-did interface-related code to emulate getifaddrs/freeifaddrs for
restricting usage to only active, multicast-capable, and non-point-to-point interfaces and to ease
the addition of IPv6 support in the future; Changed init code to serialize thread initialization to
enable ThreadID improvement to wakeup notification; Define platform support structure locally to
allow portable mDNS_Init usage; Removed dependence on modified mDNSCore: define interface ID<->name
structures/prototypes locally; Changed to use _beginthreadex()/_endthreadex() on non-Windows CE
platforms (re-mapped to CreateThread on Window CE) to avoid a leak in the Microsoft C runtime;
Added IPv4/IPv6 string<->address conversion routines; Cleaned up some code and added HeaderDoc.

Revision 1.8  2003/08/12 19:56:27  cheshire
Update to APSL 2.0

Revision 1.7  2003/07/23 02:23:01  cheshire
Updated mDNSPlatformUnlock() to work correctly, now that <rdar://problem/3160248>
"ScheduleNextTask needs to be smarter" has refined the way m->NextScheduledEvent is set

Revision 1.6  2003/07/02 21:20:04  cheshire
<rdar://problem/3313413> Update copyright notices, etc., in source code comments

Revision 1.5  2003/04/29 00:06:09  cheshire
<rdar://problem/3242673> mDNSWindows needs a wakeupEvent object to signal the main thread

Revision 1.4  2003/03/22 02:57:44  cheshire
Updated mDNSWindows to use new "mDNS_Execute" model (see "mDNSCore/Implementer Notes.txt")

Revision 1.3  2002/09/21 20:44:54  zarzycki
Added APSL info

Revision 1.2  2002/09/20 05:55:16  bradley
Multicast DNS platform plugin for Win32
