# ldns\_rr\_get\_class(3)

access rdata fields on ldns\_rr

## NAME

ldns\_rr\_rdf, ldns\_rr\_owner, ldns\_rr\_rd\_count, ldns\_rr\_ttl, ldns\_rr\_get\_class - access rdata fields on ldns\_rr

## SYNOPSIS

\#include \<stdint.h\>\
 \#include \<stdbool.h\>\

\#include \<ldns/ldns.h\>

ldns\_rdf\* ldns\_rr\_rdf(const ldns\_rr \*rr, size\_t nr);

ldns\_rdf\* ldns\_rr\_owner(const ldns\_rr \*rr);

size\_t ldns\_rr\_rd\_count(const ldns\_rr \*rr);

uint32\_t ldns\_rr\_ttl(const ldns\_rr \*rr);

ldns\_rr\_class ldns\_rr\_get\_class(const ldns\_rr \*rr);

## DESCRIPTION

*ldns\_rr\_rdf*() returns the rdata field member counter. .br **\*rr**: rr to operate on .br **nr**: the number of the rdf to return .br Returns ldns\_rdf \*

*ldns\_rr\_owner*() returns the owner name of an rr structure. .br **\*rr**: rr to operate on .br Returns ldns\_rdf \*

*ldns\_rr\_rd\_count*() returns the rd\_count of an rr structure. .br **\*rr**: the rr to read from .br Returns the rd count of the rr

*ldns\_rr\_ttl*() returns the ttl of an rr structure. .br **\*rr**: the rr to read from .br Returns the ttl of the rr

*ldns\_rr\_get\_class*() returns the class of the rr. .br **\*rr**: the rr to read from .br Returns the class of the rr
