$Log: helper.h,v $
Revision 1.18  2009/04/20 20:40:14  cheshire
<rdar://problem/6786150> uDNS: Running location cycling caused configd and mDNSResponder to deadlock
Changed mDNSPreferencesSetName (and similar) routines from MIG "routine" to MIG "simpleroutine"
so we don't deadlock waiting for a result that we're just going to ignore anyway

Revision 1.17  2009/03/20 22:12:28  mcguire
<rdar://problem/6703952> Support CFUserNotificationDisplayNotice in mDNSResponderHelper
Make the call to the helper a simpleroutine: don't wait for an unused return value

Revision 1.16  2009/03/20 20:52:22  cheshire
<rdar://problem/6703952> Support CFUserNotificationDisplayNotice in mDNSResponderHelper

Revision 1.15  2009/03/14 01:42:56  mcguire
<rdar://problem/5457116> BTMM: Fix issues with multiple .Mac accounts on the same machine

Revision 1.14  2009/01/22 02:14:27  cheshire
<rdar://problem/6515626> Sleep Proxy: Set correct target MAC address, instead of all zeroes

Revision 1.13  2009/01/14 01:38:43  mcguire
<rdar://problem/6492710> Write out DynamicStore per-interface SleepProxyServer info

Revision 1.12  2009/01/12 22:26:13  mkrochma
Change DynamicStore location from BonjourSleepProxy/DiscoveredServers to SleepProxyServers

Revision 1.11  2008/12/05 02:35:24  mcguire
<rdar://problem/6107390> Write to the DynamicStore when a Sleep Proxy server is available on the network

Revision 1.10  2008/11/04 23:54:09  cheshire
Added routine mDNSSetARP(), used to replace an SPS client's entry in our ARP cache with
a dummy one, so that IP traffic to the SPS client initiated by the SPS machine can be
captured by our BPF filters, and used as a trigger to wake the sleeping machine.

Revision 1.9  2008/10/24 01:42:36  cheshire
Added mDNSPowerRequest helper routine to request a scheduled wakeup some time in the future

Revision 1.8  2008/10/20 22:01:28  cheshire
Made new Mach simpleroutine "mDNSRequestBPF"

Revision 1.7  2008/09/27 00:58:11  cheshire
Added mDNSRequestBPF declaration

Revision 1.6  2007/09/20 22:33:17  cheshire
Tidied up inconsistent and error-prone naming -- used to be mDNSResponderHelper in
some places and mDNSResponder.helper in others; now mDNSResponderHelper everywhere

Revision 1.5  2007/09/07 22:44:03  mcguire
<rdar://problem/5448420> Move CFUserNotification code to mDNSResponderHelper

Revision 1.4  2007/09/04 22:32:58  mcguire
<rdar://problem/5453633> BTMM: BTMM overwrites /etc/racoon/remote/anonymous.conf

Revision 1.3  2007/08/23 21:51:44  cheshire
Made code layout style consistent with existing project style; added $Log header

Revision 1.1  2007/08/08 22:34:58  mcguire
<rdar://problem/5197869> Security: Run mDNSResponder as user id mdnsresponder instead of root
