✨ NAME ✨

dns_name_packet(3) — pull names out of a DNS answer packet. That’s the whole vibe, bestie. This one lives in the Library Functions Manual and it’s giving low-level DNS realness.

🌸 SYNTAX 🌸

#include <libowfat/dns.h>

int dns_name_packet(stralloc* out,const char* buf,
                    unsigned int len);

💖 DESCRIPTION 💖

okay so dns_name_packet is a low-level component of dns_name4, and it was designed to support asynchronous DNS lookups. no cap.

Here’s the tea, fr fr: it reads a DNS packet of length len from buf, extracts the first PTR record from the answer section of the packet, puts the result into out, and returns 0 or -1 the exact same way dns_name4 does. periodt. 💅

🔥 SEE ALSO 🔥

this page comes from the Library Functions Manual, and the footer just signs off as dns_name_packet(3) — no extra date/version energy, just that. bye bestie 💖🦋
