✨ NAME ✨

dns_txt_packet — extract TXT records from DNS answer packet

like... that's literally the whole job description. iconic behavior tbh 👑

---

🎀 SYNTAX 🎀

#include <libowfat/dns.h>

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

yes the indentation is a little quirky, we don't gatekeep 🫶

🦋 DESCRIPTION 🦋

okay so listen. dns_txt_packet is a low-level component of dns_txt — think of dns_txt as the main character and dns_txt_packet as the bestie backstage making it all happen 💅

she's specifically designed to support asynchronous DNS lookups, which is giving very "I don't wait around, I do things on my own schedule" energy.

here's the whole vibe:

• she reads a DNS packet of length len from buf 📦
• she extracts the TXT records from the answer section of the packet
• she puts the result into out
• she returns 0 or -1 — the same way as dns_txt

that's it. that's the function. no drama, just results ✨

heads up: the 0 / -1 return convention is exactly whatever dns_txt does — she's not out here inventing her own rules, she's just the low-level girlie following the same playbook 📖
