ldns(3)

💖 ldns(3) — the ldns library, bestie edition 🦋

okay so this is a page from the ldns(3) manual, and it's specifically about one little function that wants to be getaddrinfo() when it grows up. it's giving "library functions manual" energy and we are OBSESSED. let's get into it 💅

✨ NAME ✨

ldns_getaddrinfo — mimic libc getaddrinfo

like. it literally says "mimic". it's a tribute act. a cover band. and honestly? it ate. 🎤

---

🌸 SYNOPSIS 🌸

#include <stdint.h>
#include <stdbool.h>

#include <ldns/ldns.h>

uint16_t ldns_getaddrinfo(ldns_resolver *res, const ldns_rdf *node,
ldns_rr_class c, ldns_rr_list **list);

no cap, those includes are mandatory, she's not optional about it 🎀

---

🧚 DESCRIPTION 🧚

so ldns_getaddrinfo() is a wrapper function for ldns_get_rr_list_name_by_addr and ldns_get_rr_list_addr_by_name. it's basically the group chat admin of those two — it just handles the vibes so you don't have to 😌

and yeah, the name is straight up borrowed from the getaddrinfo() library call. it tries to mimic that call, but — and this is the important part, bestie — without the lowlevel stuff. so it's getaddrinfo() but in a cute little cardigan. 💜

here's the rundown of the arguments, periodt:

• res — the resolver. if this value is NULL then a resolver will be created by ldns_getaddrinfo. yes, it'll just make one for you. main character behaviour fr fr 👑
• node — the name or ip address to look up. that's the thing you're curious about 🔍
• c — the class to look in. y'know, the class class 🎀
• list — put the found RR's in this list. she's your output bucket, hand her over 💖

Returns the number of RR found. that's the whole point. that's the answer. count it and slay. ✨
