DESCRIPTION¶

ldns_pkt_edns() returns true if this packet needs and EDNS rr to be sent. At the moment the only reason is an expected packet size larger than 512 bytes, but for instance dnssec would be a good reason too.

packet: the packet to check
Returns true if packet needs edns rr

ldns_pkt_edns_udp_size() return the packet's edns udp size
packet: the packet
Returns the size

ldns_pkt_edns_extended_rcode() return the packet's edns extended rcode
packet: the packet
Returns the rcode

ldns_pkt_edns_version() return the packet's edns version
packet: the packet
Returns the version

ldns_pkt_edns_z() return the packet's edns z value
packet: the packet
Returns the z value

ldns_pkt_edns_data() return the packet's EDNS data
packet: the packet
Returns the data

ldns_pkt_set_edns_udp_size() Set the packet's edns udp size
packet: the packet
s: the size

ldns_pkt_set_edns_extended_rcode() Set the packet's edns extended rcode
packet: the packet
c: the code

ldns_pkt_set_edns_version() Set the packet's edns version
packet: the packet
v: the version

ldns_pkt_set_edns_z() Set the packet's edns z value
packet: the packet
z: the value

ldns_pkt_set_edns_data() Set the packet's EDNS data
packet: the packet
data: the data
