ldns(3)

✨ ldns(3) ✨ — it's giving "Library Functions Manual", bestie 💅

okay so you found yourself in the ldns(3) manual, which means you're deep in DNS-adjacent C code and honestly? iconic behavior. sit down, hydrate, let's get into it 🫶

🎀 NAME 🎀

ldns_buffer2pkt_wire — convert buffer/wire format to ldns_pkt

like, that's the whole job description. one function. one destiny. main character energy fr fr 💖

---

🌸 SYNOPSIS 🌸

so this is how you actually pull it into your code, no cap:

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

#include <ldns/ldns.h>

ldns_status ldns_buffer2pkt_wire(ldns_pkt **packet, const ldns_buffer
*buffer);

look at those includes. stdint.h and stdbool.h are just vibing up there, and then the real one: ldns/ldns.h. that's your girl. that's where everything lives 💜

---

🦋 DESCRIPTION 🦋

ldns_buffer2pkt_wire() takes the data sitting in your ldns_buffer — which is in wire format, aka the raw on-the-wire byte soup — and converts it into a proper DNS packet. 🎀

and bestie, important detail: this function will initialize and allocate memory space for the packet structure. so it's not just filling in something you already made — it's setting it up for you. obsessed with a function that does the heavy lifting. 💅

here's what the args are giving:

• packet — pointer to the structure that's gonna hold the packet
• buffer — the buffer with the data
• Returns LDNS_STATUS_OK if everything succeeds, and an error otherwise 😭

so like, always check that return value, okay? LDNS_STATUS_OK means we ate. anything else means something went sideways and you should go look at it. 🙈
