KNET_HOST_GET_POLICY(3)

💖 KNET_HOST_GET_POLICY 💖

okay so bestie, this is a page from the Kronosnet Programmer's Manual (that's the kronosnet crew, and yes they are iconic for it) — and today we're getting into knet_host_get_policy(3). it's the lil function that spills the tea on which switching policy a host's links are using. no cap. 🫶

---

✨ NAME ✨

knet_host_get_policy — Get the switching policy for a host's links.

---

🎀 SYNOPSIS 🎀

#include <libknet.h>

int knet_host_get_policy(
    knet_handle_t   knet_h,
    knet_node_id_t  host_id,
    uint8_t        *policy
);

---

🦋 DESCRIPTION 🦋

okay so here's the whole vibe. knet_host_get_policy — that's the main character of this page — and here's what you hand it:

• knet_h — pointer to knet_handle_t. yeah, the handle, your little entry ticket to everything.
• host_id — see knet_host_add(3). that's where the lore lives.
• policy — this one's an output, bestie. it will contain the current configured switching policy. and just so you're not surprised later: the default is passive when you create a new host. periodt. 💅

---

🔥 RETURN VALUE 🔥

knet_host_get_policy returns 0 on success, and -1 on error — and when it errors out, errno gets set. so like, check it. don't just vibe past it. 😭
