ldns(3)

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

okay so welcome to the ldns(3) page, aka the library functions manual where we get to poke at ldns_rr structs and pull their little fields out one by one. this is the glow-up guide to reading rdata fields, no cap. 🎀

---

✨ NAME ✨

ldns_rr_rdf, ldns_rr_owner, ldns_rr_rd_count, ldns_rr_ttl, ldns_rr_get_class — access rdata fields on ldns_rr

like… they're all just lil accessor girlies for your resource records. 💅

---

🌸 SYNOPSIS 🌸

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

#include <ldns/ldns.h>

ldns_rdf* ldns_rr_rdf(const ldns_rr *rr, size_t nr);

ldns_rdf* ldns_rr_owner(const ldns_rr *rr);

size_t ldns_rr_rd_count(const ldns_rr *rr);

uint32_t ldns_rr_ttl(const ldns_rr *rr);

ldns_rr_class ldns_rr_get_class(const ldns_rr *rr);

look at those signatures. immaculate. ✨ copy them exactly, bestie, we do not freestyle headers in this house.

🦋 DESCRIPTION 🦋

• ldns_rr_rdf() returns the rdata field member counter. 🍓
  • *rr: rr to operate on
  • nr: the number of the rdf to return
  • Returns ldns_rdf *
• ldns_rr_owner() returns the owner name of an rr structure. 👑
  • *rr: rr to operate on
  • Returns ldns_rdf *
• ldns_rr_rd_count() returns the rd_count of an rr structure. 🔢
  • *rr: the rr to read from
  • Returns the rd count of the rr
• ldns_rr_ttl() returns the ttl of an rr structure. ⏳
  • *rr: the rr to read from
  • Returns the ttl of the rr
• ldns_rr_get_class() returns the class of the rr. 🏷️
  • *rr: the rr to read from
  • Returns the class of the rr

the way that all of these just take one const ldns_rr * and hand you back a field… lowkey the most chill API ever. they don't mutate anything, they just read. main character energy tbh. 💜
