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