59Renamed mDNSClientAPI.h to mDNSEmbeddedAPI.h
60 The name "mDNSClientAPI.h" is misleading to new developers looking at this code. The interfaces
61 declared in that file are ONLY appropriate to single-address-space embedded applications.
62 For clients on general-purpose computers, the interfaces defined in dns_sd.h should be used.

83to avoid shared memory issues. Added a routine to free the list.

85Revision 1.33 2004/05/12 02:03:25 ksekar
86Non-local domains will only be browsed by default, and show up in

7f0064bd 161<rdar://problem/3249292>: Feature: New DNS-SD APIs (#7875)
c9b9ae52
A		 162Reviewed by: Stuart Cheshire
163Added files necessary to implement Unix domain sockets based enhanced
7f0064bd 164DNS-SD APIs, and integrated with existing Mach-port based daemon.

166Revision 1.9 2003/06/10 01:14:11 cheshire

168
169Revision 1.8 2003/05/14 07:08:37 cheshire
170<rdar://problem/3159272> mDNSResponder should be smarter about reconfigurations
171Previously, when there was any network configuration change, mDNSResponder
172would tear down the entire list of active interfaces and start again.
173That was very disruptive, and caused the entire cache to be flushed,
174and caused lots of extra network traffic. Now it only removes interfaces
175that have really gone, and only adds new ones that weren't there before.
176
177Revision 1.7 2003/04/26 02:39:24 cheshire
178Remove extern void LogMsg(const char *format, ...);
