New Revision: 26703
URL: http://svn.reactos.org/svn/reactos?rev=26703&view=rev
Log:
- Move CmpCreateRootNode and CmpCreateRegistryRoot to cmsysini.c as well, and add some
fixes to CmpCreateRegistryRoot to make it compatible with the Cm Rewrite when it's
done.
- Initialize some stuff that wasn't being initialized in CmpCreateRootNode.
- Use CmpHiveRootSecurityDescriptor in CmpCreateRegistryRoot to protect the key.
- Save the root handle globally so we can close it during shutdown.
- Add cmkcbncb.c with an empty stub for CmpCreateKeyControlBlock. Will copy from Cm
rewrite branch later.
- Properly name fields of CM_KEY_NODE in the headers of the /config tree.
