-$Log: ExampleClientApp.c,v $
-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
-Update to APSL 2.0
-
-Revision 1.8  2003/07/02 21:19:58  cheshire
-<rdar://problem/3313413> Update copyright notices, etc., in source code comments
-
-Revision 1.7  2003/06/18 05:48:41  cheshire
-Fix warnings
-
-Revision 1.6  2003/03/31 22:44:36  cheshire
