ldns(3)

💖 ldns(3) — the library functions manual, bestie edition 💖

okay so you opened the manpage for ldns, the DNS library, and honestly? slay. this one's a lil bite-sized function but she's important, so let's get into it. 🎀

---

✨ NAME ✨

ldns_dname2canonical — canonicalize a dname. that's it, that's the whole vibe. 💅

---

🌸 SYNOPSIS 🌸

first you gotta pull in the headers, no cap:

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

#include <ldns/ldns.h>

void ldns_dname2canonical(const ldns_rdf *rdf);

look at her. void return, one const ldns_rdf * argument, zero drama. 👑

---

🦋 DESCRIPTION 🦋

so ldns_dname2canonical() takes a dname and puts it into canonical fmt — meaning it lowercases it. that's the whole job, bestie. she's a lowercase girlie and she's thriving. ✨

• rdf — the dname to lowercase 🫶
• Returns void. literally nothing comes back. not a value, not an error code, nothing. she does the thing and she leaves. main character energy fr fr. 💀

ngl this is one of those functions where the side effect is the point — the rdf you handed in comes out lowercase. don't go looking for a return value, there isn't one. 🙈
