.SH DESCRIPTION
|
||
|
|
dns_ip4_packet is a low-level component of dns_ip4, designed to support
|
||
|
|
asynchronous DNS lookups. It reads a DNS packet of length \fIlen\fR from
|
||
|
|
\fIbuf\fR, extracts IP addresses from the answer section of the packet,
|
||
|
|
puts the addresses into \fIout\fR, and returns 0 or -1 the same way as
|
||
|
|
dns_ip4.
