## DESCRIPTION

*ldns\_rr\_dnskey\_flags*() returns the flags of a LDNS\_RR\_TYPE\_DNSKEY rr .br **r**: the resource record .br Returns a ldns\_rdf\* with the flags or NULL on failure

*ldns\_rr\_dnskey\_set\_flags*() sets the flags of a LDNS\_RR\_TYPE\_DNSKEY rr .br **r**: the rr to use .br **f**: the flags to set .br Returns true on success, false otherwise

*ldns\_rr\_dnskey\_protocol*() returns the protocol of a LDNS\_RR\_TYPE\_DNSKEY rr .br **r**: the resource record .br Returns a ldns\_rdf\* with the protocol or NULL on failure

*ldns\_rr\_dnskey\_set\_protocol*() sets the protocol of a LDNS\_RR\_TYPE\_DNSKEY rr .br **r**: the rr to use .br **f**: the protocol to set .br Returns true on success, false otherwise

*ldns\_rr\_dnskey\_algorithm*() returns the algorithm of a LDNS\_RR\_TYPE\_DNSKEY rr .br **r**: the resource record .br Returns a ldns\_rdf\* with the algorithm or NULL on failure

*ldns\_rr\_dnskey\_set\_algorithm*() sets the algorithm of a LDNS\_RR\_TYPE\_DNSKEY rr .br **r**: the rr to use .br **f**: the algorithm to set .br Returns true on success, false otherwise

*ldns\_rr\_dnskey\_key*() returns the key data of a LDNS\_RR\_TYPE\_DNSKEY rr .br **r**: the resource record .br Returns a ldns\_rdf\* with the key data or NULL on failure

*ldns\_rr\_dnskey\_set\_key*() sets the key data of a LDNS\_RR\_TYPE\_DNSKEY rr .br **r**: the rr to use .br **f**: the key data to set .br Returns true on success, false otherwise
