resource record pertains.</pre><pre>TYPE two octets containing one of the RR TYPE codes.</pre><pre>CLASS two octets containing one of the RR CLASS codes.</pre><pre>TTL a 32 bit signed integer that specifies the time interval
that the resource record may be cached before the source
of the information should again be consulted. Zero
values are interpreted to mean that the RR can only be
used for the transaction in progress, and should not be
cached. For example, SOA records are always distributed
with a zero TTL to prohibit caching. Zero values can
also be used for extremely volatile data.</pre><pre>RDLENGTH an unsigned 16 bit integer that specifies the length in
octets of the RDATA field.</pre><pre>RDATA a variable length string of octets that describes the
resource. The format of this information varies
according to the TYPE and CLASS of the resource record.
</pre><p>The actual amount and type of rdata fields depend on the RR type of the RR, and can be found by using <a class="el" href="rr_8h.html#afa0d945577e168e23b567d68b04ba5cd">ldns_rr_descriptor</a> functions. </p>
