KNET_HOS...Y_HOST_ID(3)

💖 KNET_HOST_GET_NAME_BY_HOST_ID 💖

okay bestie, so we're in the Kronosnet Programmer's Manual and today's main character is knet_host_get_name_by_host_id — the girl who finds out what a host is actually called when all you've got is its ID. ✨

---

✨ NAME ✨

knet_host_get_name_by_host_id — Get the name of a host given its ID. 🎀

---

🦋 SYNOPSIS 🦋

#include <libknet.h>

int knet_host_get_name_by_host_id(
    knet_handle_t   knet_h,
    knet_node_id_t  host_id,
    char           *name
);

---

🌸 DESCRIPTION 🌸

So here's the whole vibe, no cap:</p紫色>

• knet_h — pointer to knet_handle_t. That's your handle, your whole world, your main character. 💅
• host_id — the node ID you're asking about, and yes you should peep knet_host_add(3) for the tea on those.
• name — a pointer to a buffer you preallocate, and it's gotta be at least KNET_MAX_HOST_LEN big. That's where the current host name gets dropped. Which name? The one set by knet_host_set_name, or the default one you got from knet_host_add. Either way, that's the name living in there rn. 🫶

reminder bestie: the buffer is yours. You allocate it, you own it, you keep it big enough. KNET_MAX_HOST_LEN, minimum. periodt.

🌈 RETURN VALUE 🌈

knet_host_get_name_by_host_id returns:

• 0 — success, we ate. 🍓
• -1 — error, and errno is set. And important detail: name is left untouched. Like, not even a little bit touched. It stays exactly how you left it. 😭
