ldns(3)

💖 ldns — the ldns_rr_compare files, bestie 💖

okay so like, this is a page from the ldns library manual (section 3, library functions, you know the vibe ✨). It's all about comparing resource records with each other. Two little functions. Both of them adorable. Both of them very serious about their job. Let's get into it 🫶

🌸 NAME 🌸

ldns_rr_compare, ldns_rr_compare_ds — compare a ldns_rr 💅

---

✨ SYNOPSIS ✨

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

#include <ldns/ldns.h>

int ldns_rr_compare(const ldns_rr *rr1, const ldns_rr *rr2);

bool ldns_rr_compare_ds(const ldns_rr *rr1, const ldns_rr *rr2);

like, that's it. two functions. both of them just wanna know: are these two the same? 👀

🦋 DESCRIPTION 🦋

💜 ldns_rr_compare()

This one compares two rrs. And here's the thing, bestie — the TTL is not looked at. Not even a little. Not even a peek. It is simply not part of the vibe check 🚫✨

• rr1 — the first one 💖
• rr2 — the second one 💖

And it returns:

• 0 if they're equal (periodt, they match 👑)
• -1 if rr1 comes before rr2
• +1 if rr2 comes before rr1

So it's not a yes/no situation, it's a "who's first" situation. It's giving alphabetical order energy but for records. 🎀

---

🌈 ldns_rr_compare_ds()

This one returns true if the given rr's are equal. That's the whole main character move right there. 💅

BUT WAIT, there's more — it also returns true if one record is a DS that represents the same DNSKEY record as the other record. Like, different types, same truth underneath. It's giving soulmates. 😭💜

• rr1 — the first rr
• rr2 — the second rr

Returns true if equal, otherwise false. That's it. Clean. Simple. Iconic. ✨
