KNET_HOST_SET_NAME(3)

💖 NAME 💖

knet_host_set_name — bestie, this is the one that gives a knet host an actual name. Like a glow-up but for your node IDs. ✨

---

🎀 SYNOPSIS 🎀

#include <libknet.h>

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

---

🦋 DESCRIPTION 🦋

okay so. knet_host_set_name is the function. She's giving naming rights, and honestly? iconic.

• knet_h — pointer to knet_handle_t. your handle, your girl, you know her 💅
• host_id — see knet_host_add(3). that's where you go find out what a host id even is, bestie, go read it 🫶
• name — this name will be used for pretty logging and eventually search for hosts (see also knet_handle_host_get_name(2) and knet_handle_host_get_id(3)). Only up to KNET_MAX_HOST_LEN - 1 bytes will be accepted and name has to be unique for each host.

⚠️ two things, and I need you to hear me: only KNET_MAX_HOST_LEN - 1 bytes get accepted (the rest just gets yeeted, no cap), and the name has to be unique for each host. every host gets their own name. no sharing. no duplicates. that's the vibe check. 💀

---

🌸 RETURN VALUE 🌸

knet_host_set_name returns: 0 on success, -1 on error and errno is set.

so like, if you got a 0, slay, you ate. if you got -1, go check errno, she's telling you what went wrong 🎀
