dns_ip6_packet(3)

✨ dns_ip6_packet ✨ — it's giving Library Functions Manual energy, bestie

okay so real talk, this is dns_ip6_packet(3), and she is a whole vibe. let's get into it 🫶

💖 NAME 💖

dns_ip6_packet — extract IPv6 address from DNS answer packet

yes she says IPv6 in the name and then talks about IPv4 too in a sec. that's just how she is. no cap. 🙈

🎀 SYNTAX 🎀

#include <libowfat/dns.h>

int dns_ip6_packet(stralloc* out,const char* buf,
                   unsigned int len);

like, that's the whole signature. three args. she's lowkey minimalist. 💅

🌸 DESCRIPTION 🌸

so dns_ip6_packet is a low-level component of dns_ip6, and the reason she exists at all is to support asynchronous DNS lookups. queen of doing one job really well. 👑

here's what she actually does:

• reads a DNS packet of length len from buf 📦
• extracts IPv4 and IPv6 addresses from the answer section of the packet 🔍
• puts the addresses into out 💌
• returns 0 or -1 the same way as dns_ip6 🎯

and that's it. that's the whole thing. she's not out here doing extra. no drama, just packets. ✨
