The KEY_NODE_INFORMATION structure defines the basic information available for a registry (sub)key.

typedef struct _KEY_NODE_INFORMATION {
  LARGE_INTEGER  LastWriteTime;
  ULONG  TitleIndex;
  ULONG  ClassOffset;
  ULONG  ClassLength;
  ULONG  NameLength;
  WCHAR  Name[1];  //  Variable-length string
} KEY_NODE_INFORMATION, *PKEY_NODE_INFORMATION;
