31 $Log: uds_daemon.h,v $
32 Revision 1.14 2005/01/27 17:48:39 cheshire
33 Added comment about CFSocketInvalidate closing the underlying socket
34
35 Revision 1.13 2004/12/10 05:27:26 cheshire
36 <rdar://problem/3909147> Guard against multiple autoname services of the same type on the same machine
37
38 Revision 1.12 2004/12/10 04:28:28 cheshire
39 <rdar://problem/3914406> User not notified of name changes for services using new UDS API
40
41 Revision 1.11 2004/12/06 21:15:23 ksekar
42 <rdar://problem/3884386> mDNSResponder crashed in CheckServiceRegistrations
43
44 Revision 1.10 2004/10/26 04:31:44 cheshire
45 Rename CountSubTypes() as ChopSubTypes()
46
47 Revision 1.9 2004/09/30 00:25:00 ksekar
48 <rdar://problem/3695802> Dynamically update default registration domains on config change
49
50 Revision 1.8 2004/09/21 21:05:11 cheshire
51 Move duplicate code out of mDNSMacOSX/daemon.c and mDNSPosix/PosixDaemon.c,
52 into mDNSShared/uds_daemon.c
53
54 Revision 1.7 2004/09/17 01:08:55 cheshire
55 Renamed mDNSClientAPI.h to mDNSEmbeddedAPI.h
56 The name "mDNSClientAPI.h" is misleading to new developers looking at this code. The interfaces
57 declared in that file are ONLY appropriate to single-address-space embedded applications.
58 For clients on general-purpose computers, the interfaces defined in dns_sd.h should be used.
59
60 Revision 1.6 2004/08/11 01:58:49 cheshire
61 Remove "mDNS *globalInstance" parameter from udsserver_init()
62
63 Revision 1.5 2004/06/18 04:44:58 rpantos
64 Use platform layer for socket types
65
66 Revision 1.4 2004/06/12 00:51:58 cheshire
67 Changes for Windows compatibility
68
69 Revision 1.3 2004/01/25 00:03:21 cheshire
70 Change to use mDNSVal16() instead of private PORT_AS_NUM() macro
71
72 Revision 1.2 2004/01/24 08:46:26 bradley
73 Added InterfaceID<->Index platform interfaces since they are now used by all platforms for the DNS-SD APIs.
74
75 Revision 1.1 2003/12/08 21:11:42 rpantos;
76 Changes necessary to support mDNSResponder on Linux.
