KNET_HANDLE_SETFWD(3)

✨ KNET_HANDLE_SETFWD 💅

okay so bestie, we're reading the Kronosnet Programmer's Manual today, and the page is KNET_HANDLE_SETFWD(3) — literally the switch that makes the packets actually GO. 🦋

---

🌸 NAME 🌸

knet_handle_setfwd — Start packet forwarding.

like, that's it, that's the whole job. it flips the "yes actually send the traffic" bit. 👑

---

✨ SYNOPSIS ✨

#include <libknet.h>

int knet_handle_setfwd(
    knet_handle_t  knet_h,
    unsigned int   enabled
);

---

💖 DESCRIPTION 💖

knet_handle_setfwd — the function itself, the main character. 🌟

• knet_h — pointer to knet_handle_t. that's your handle, your little baby, your whole networking world. 🫶
• enable — set to 1 to allow data forwarding, 0 to disable data forwarding. on or off. slay or stay home. 💅

no cap: by default data forwarding is off, and no traffic will pass through knet until it is set on. so if you're sitting there like "why is nothing flowing 😭" — it's this. it's always this. turn it on bestie.

---

🔥 RETURN VALUE 🔥

knet_handle_setfwd returns 0 on success, -1 on error, and errno is set. classic. iconic. predictable. ⭐
