💖 ldns — the string-conversion girlies 💖

okay so bestie, welcome to the ldns(3) manual page, from the Library Functions Manual, and honestly? this one is a whole vibe. it's the conversions to string page. that's it. that's the girl. she takes your DNS stuff and turns it into pretty text so you can actually read it with your eyeballs. slay. ✨

✨ NAME ✨

ldns_rr2str, ldns_pkt2str, ldns_rdf2str, ldns_rr_list2str, ldns_key2str — functions for conversions to string 🎀

🦋 SYNOPSIS 🦋

like, here's the whole cast, no cap:

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

#include <ldns/ldns.h>

char* ldns_rr2str(const ldns_rr *rr);

char* ldns_pkt2str(const ldns_pkt *pkt);

char* ldns_rdf2str(const ldns_rdf *rdf);

char* ldns_rr_list2str(const ldns_rr_list *rr_list);

char* ldns_key2str(const ldns_key *k);

💅 DESCRIPTION 💅

five little functions, all of them doing the same iconic thing: giving you back a char * with presentation format in it. and literally every single one of them comes with the same reminder, so I'm gonna say it once and mean it five times: remember to free it. she's giving you memory, bestie. she's not taking it back. 🫶
