<hr><a name="_details"></a><h2>Detailed Description</h2>
This structure contains an RRset.
<p>
A set of resource records that share the same domain name, type and class.<p>
Due to memory management and threading, the key structure cannot be deleted, although the data can be. The id can be set to 0 to store and the structure can be recycled with a new id. <hr><h2>Field Documentation</h2>
