KNET_LINK...ONG_COUNT(3)

💖 KNET_LINK_GET_PONG_COUNT — bestie edition 💖

okay so this is a page from the Kronosnet Programmer's Manual, and it's about one (1) little function that goes and fetches the pong count for a link. yes, pong. like ping-pong. we're doing networking, we're being cute about it, we're keeping every single fact. let's GO 🏓✨

🌸 NAME 🌸

knet_link_get_pong_count — get the pong count for a link. that's it, that's the whole job, and she does it flawlessly 💅

---

🦋 SYNOPSIS 🦋

#include <libknet.h>

int knet_link_get_pong_count(
    knet_handle_t   knet_h,
    knet_node_id_t  host_id,
    uint8_t         link_id,
    uint8_t        *pong_count
);

---

✨ DESCRIPTION ✨

so knet_link_get_pong_count is the function, and here's literally everyone in the cast:

• knet_h — pointer to knet_handle_t. the main character handle, no cap.
• host_id — see knet_host_add(3). she's the node you're asking about 🫶
• link_id — see knet_link_set_config(3). which link on that host, bestie.
• pong_count — how many valid ping/pongs before a link is marked UP. default: 5, and the value should be > 0. so like. five. that's the vibe. not zero, never zero, zero is not the moment 🙈

---

🎀 RETURN VALUE 🎀

knet_link_get_pong_count returns 0 on success, -1 on error, and errno is set. that's it. 0 = slay, -1 = check errno, periodt. 😭
