dns_ip4_packet(3)

okay bestie, welcome to dns_ip4_packet(3) from the Library Functions Manual — she's niche, she's low-level, and she's here to help you pull IPv4 addresses out of DNS packets 💅✨

🌸 NAME 🌸

dns_ip4_packet — extract IPv4 address from DNS answer packet 🎀

🦋 SYNTAX 🦋

#include <libowfat/dns.h>

int dns_ip4_packet(stralloc* out,const char* buf,
                   unsigned int len);

✨ DESCRIPTION ✨

So dns_ip4_packet is a low-level component of dns_ip4, and she was literally designed to support asynchronous DNS lookups. main character energy fr fr 🫶

She reads a DNS packet of length len from buf, extracts IP addresses from the answer section of the packet, puts the addresses into out, and returns 0 or -1 the same way as dns_ip4. no cap, that's the whole vibe 🌈

bestie, this is the packet-level bestie behind the scenes — she's not doing the whole DNS conversation, just handling the packet part like the icon she is 💖
