This structure of pointers configures the Dynamic DNS Client. Initially, all pointers will be null and the client will be disabled. Set DDNSClient.[field name].szRAM to use a string stored in RAM, or DDNSClient.[field name].szROM to use a string stored in ROM. (Where [field name] is one of the parameters below.) 

If a ROM string is specified, DDNSClient.ROMPointers.[field name] must also be set to 1 to indicate that this field should be retrieved from ROM instead of RAM.
