+ * What's all of this stuff about???
+ *
+ * In order to minimize the amount of data conversions associated with
+ * storing, retrieving, and accessing the systems DNS configuration I
+ * have opted to create a memory image filled with the actual data
+ * types / structures that would be used by those applications which
+ * make use of these APIS.  The implication here is that we use
+ * sockaddr's for addresses, char *'s for strings, etc.
+ *
+ * To achieve this goal the APIs which are used to store and access the
+ * configuration data build and use a single buffer of the relevant
+ * bits.  When multiple instances of a given type / structure are needed
+ * we maintain a count, the actual data, and when the configuration has
+ * been unpacked, arrays of pointers to the data.
+ *
+ * In memory, the data looks as follows:
+ *
