KNET_LINK..._PRIORITY(3)

💖 knet_link_set_priority 💖

okay bestie, welcome to the Kronosnet Programmer's Manual — yes it's a real manual, yes it's about network links, yes you're gonna slay it. this page is literally just about giving a link a priority, and i'm obsessed with how simple it is. 🎀

✨ NAME ✨

knet_link_set_priority — set the priority for a link. that's it. that's the whole vibe. 💅

🌸 SYNOPSIS 🌸

#include <libknet.h>

int knet_link_set_priority(
    knet_handle_t   knet_h,
    knet_node_id_t  host_id,
    uint8_t         link_id,
    uint8_t         priority
);

like, look at her. four little args, one big job. main character energy fr fr. 👑

🦋 DESCRIPTION 🦋

so we're calling knet_link_set_priority, and here's the tea on every single argument, no cap:

• knet_h — pointer to knet_handle_t. this is your handle, your anchor, the whole reason you're here.
• host_id — see knet_host_add(3). go check that page if you need the deets. 🫶
• link_id — see knet_link_set_config(3). same deal, that's where link ids come from.
• priority — specify the switching priority for this link, see also knet_host_set_policy. that's the part that decides who gets picked when, so like... choose wisely bestie.

---

🔥 RETURN VALUE 🔥

• knet_link_set_priority returns 0 on success
• returns -1 on error, and errno is set

so yeah, if you get a 0 you ate. if you get a -1, check errno, that's your clue. 💀
