.SH DESCRIPTION
.HP
\fIldns_pkt_edns\fR()
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.

\.br
\fBpacket\fR: the packet to check
\.br
Returns true if packet needs edns rr
.PP
.HP
\fIldns_pkt_edns_udp_size\fR()
return the packet's edns udp size
\.br
\fBpacket\fR: the packet
\.br
Returns the size
.PP
.HP
\fIldns_pkt_edns_extended_rcode\fR()
return the packet's edns extended rcode
\.br
\fBpacket\fR: the packet
\.br
Returns the rcode
.PP
.HP
\fIldns_pkt_edns_version\fR()
return the packet's edns version
\.br
\fBpacket\fR: the packet
\.br
Returns the version
.PP
.HP
\fIldns_pkt_edns_z\fR()
return the packet's edns z value
\.br
\fBpacket\fR: the packet
\.br
Returns the z value
.PP
.HP
\fIldns_pkt_edns_data\fR()
return the packet's \%EDNS data
\.br
\fBpacket\fR: the packet
\.br
Returns the data

.PP
.HP
\fIldns_pkt_set_edns_extended_rcode\fR()
Set the packet's edns extended rcode
\.br
\fBpacket\fR: the packet
\.br

Set the packet's edns z value
\.br
\fBpacket\fR: the packet
\.br
\fBz\fR: the value
.PP
.HP
\fIldns_pkt_set_edns_data\fR()
Set the packet's \%EDNS data
\.br
