/* The null DNS layer is really just a minimal DNS layer. It is
* useful when you don't want to do any real DNS lookups, or when you
* want to be able to get debugging information about the requests
* flowing between DNS layers.
*
* Multiple null DNS layers can be created, which can be useful for
* debugging purposes.
*/
/*
* These routines take care of creating/destroying/etc. the objects
* that hold the DNS layer configuration. spfdcid objects contain
* malloc'ed data, so they must be destroyed when you are finished
* with them, or you will leak memory.
*/
/*
* if debugging is enabled, information about the DNS queries sent to
* the lower DNS layer, and the results returned from that layer will
* be displayed.
*
* The "name" will be used when displaying debugging information so
* that you can tell which location in the stack of DNS layers
* generated the output.
