KNET_LINK_SET_ENABLE(3)

✨ KNET_LINK_SET_ENABLE(3) ✨

okay bestie, welcome to the Kronosnet Programmer's Manual — this one's about flicking a link on and off like a light switch 💡

---

🌸 NAME 🌸

knet_link_set_enable</purpose> — enable traffic on a link. yes, that's the whole vibe. one link, on or off, you decide 💅

---

🎀 SYNOPSIS 🎀

#include <libknet.h>

int knet_link_set_enable(
    knet_handle_t   knet_h,
    knet_node_id_t  host_id,
    uint8_t         link_id,
    unsigned int    enabled
);

---

🦋 DESCRIPTION 🦋

okay so. knet_link_set_enable is the function, and here's what you're handing it:

• knet_h — a pointer to knet_handle_t. it's your handle, your main character, the whole context of the operation 🫶
• host_id — head over to knet_host_add(3) for the deets on this one, i'm not re-explaining it here
• link_id — this one's explained in knet_link_set_config(3), go peek
• enabled — the actual switch, and it's literally just 0 or 1:
  • 0 → disable the link
  • 1 → enable the link

periodt. that's the entire menu 🍓

---

💖 RETURN VALUE 💖

knet_link_set_enable returns 0 on success, and -1 on error — and when it errors, errno gets set, so go look at that instead of staring at the return value 💀
