KNET_RECV(3)

✨ KNET_RECV ✨

okay bestie, welcome to KNET_RECV(3), part of the Kronosnet Programmer's Manual 🦋 — yes this is the whole libknet cinematic universe and we're starting with the "get the data out" episode 💅

---

💖 NAME 💖

knet_recv — receive data from knet nodes. that's it, that's the gig 🎀

---

🌸 SYNOPSIS 🌸

#include <libknet.h>

ssize_t knet_recv(
    knet_handle_t  knet_h,
    char          *buff,
    const size_t   buff_len,
    const int8_t   channel
);

---

✨ DESCRIPTION ✨

so, knet_recv — here's the whole cast of characters, no skips, we're covering everything 💜

• knet_h — pointer to knet_handle_t. that's your handle, your main character, the one who knows everything 🫶
• buff — pointer to buffer to store the received data. it's literally the lil bucket you're catching the bytes in 🍓
• buff_len — buffer length. the size of the bucket. do not overflow the bucket. respectfully 🙈
• channel — channel number. which channel we're talking about, bestie 📺

---

🔥 RETURN VALUE 🔥

so here's the tea: knet_recv is a commodity function — a lil helper that wraps iovec operations around a socket, because doing that yourself is giving unnecessary labor 😭

it returns a call to readv(2). so if you know what readv(2) does, you already know what this does, periodt 👑
