-$Log: ExampleClientApp.c,v $
-Revision 1.14 2006/08/14 23:24:46 cheshire
-Re-licensed mDNSResponder daemon source code under Apache License, Version 2.0
-
-Revision 1.13 2006/02/23 23:38:43 cheshire
-<rdar://problem/4427969> On FreeBSD 4 "arpa/inet.h" requires "netinet/in.h" be included first
-
-Revision 1.12 2004/11/30 22:37:00 cheshire
-Update copyright dates and add "Mode: C; tab-width: 4" headers
-
-Revision 1.11 2004/09/17 01:08:53 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 1.10 2004/09/16 01:58:22 cheshire
-Fix compiler warnings
-
-Revision 1.9 2003/08/12 19:56:26 cheshire
