#include <dns.h>
int dns_txt_packet(stralloc* out,const char*
buf,
unsigned int len);
dns_txt_packet is a low-level component of dns_txt, designed to support asynchronous DNS lookups. It reads a DNS packet of length len from buf, extracts the TXT records from the answer section of the packet, puts the result into out, and returns 0 or -1 the same way as dns_txt.
