NAME
dns_mx_packet - extract MX records from DNS answer packet
SYNTAX
#include <libowfat/dns.h>
int
dns_mx_packet
(stralloc*
out
,const char*
buf
,
unsigned int
len
);
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 len from buf , extracts the MX records from the answer section of the packet, puts the result into out , and returns 0 or -1 the same way as dns_mx.
