# ldns\_rr\_set\_type(3)

set ldns\_rr attributes

## NAME

ldns\_rr\_set\_owner, ldns\_rr\_set\_ttl, ldns\_rr\_set\_type, ldns\_rr\_set\_rd\_count, ldns\_rr\_set\_class, ldns\_rr\_set\_rdf - set ldns\_rr attributes

## SYNOPSIS

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

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

void ldns\_rr\_set\_owner(ldns\_rr \*rr, ldns\_rdf \*owner);

void ldns\_rr\_set\_ttl(ldns\_rr \*rr, uint32\_t ttl);

void ldns\_rr\_set\_type(ldns\_rr \*rr, ldns\_rr\_type rr\_type);

void ldns\_rr\_set\_rd\_count(ldns\_rr \*rr, size\_t count);

void ldns\_rr\_set\_class(ldns\_rr \*rr, ldns\_rr\_class rr\_class);

ldns\_rdf\* ldns\_rr\_set\_rdf(ldns\_rr \*rr, const ldns\_rdf \*f, size\_t position);

## DESCRIPTION

*ldns\_rr\_set\_owner*() sets the owner in the rr structure. .br **\*rr**: rr to operate on .br **\*owner**: set to this owner .br Returns void

*ldns\_rr\_set\_ttl*() sets the ttl in the rr structure. .br **\*rr**: rr to operate on .br **ttl**: set to this ttl .br Returns void

*ldns\_rr\_set\_type*() sets the type in the rr. .br **\*rr**: rr to operate on .br **rr\_type**: set to this type .br Returns void

*ldns\_rr\_set\_rd\_count*() sets the rd\_count in the rr. .br **\*rr**: rr to operate on .br **count**: set to this count .br Returns void

*ldns\_rr\_set\_class*() sets the class in the rr. .br **\*rr**: rr to operate on .br **rr\_class**: set to this class .br Returns void

*ldns\_rr\_set\_rdf*() sets a rdf member, it will be set on the position given. The old value is returned, like pop. .br **\*rr**: the rr to operate on .br **\*f**: the rdf to set .br **position**: the position the set the rdf .br Returns the old value in the rr, NULL on failure
