KNET_HANDLE_FREE(3)

💖 KNET_HANDLE_FREE 💖

okay bestie, so this is a page from the Kronosnet Programmer's Manual — that's the libknet fam, section 3, the library calls. And this one? This one is the goodbye function. The closer. The "we had a good run, now go be free" moment. Let's get into it. 🦋

✨ NAME ✨

knet_handle_free — Destroy a knet handle, free all resources.

like, all of them. every last one. no crumbs left. 💅

---

🌸 SYNOPSIS 🌸

#include <libknet.h>

int knet_handle_free(
    knet_handle_t  knet_h
);

that's it. one include, one function, one handle, and we're done here. iconic minimalism honestly. 🎀

---

💜 DESCRIPTION 💜

knet_handle_free

• knet_h — pointer to knet_handle_t

so you hand it your handle pointer, and it goes poof. destroy the knet handle, free all resources. that's the whole vibe. it's giving cleanup era, and we love a clean exit. 🧚

---

⭐ RETURN VALUE ⭐

knet_handle_free returns 0 on success, -1 on error — and when it's the messy kind of error, errno is set. so like, check your errno bestie, she's trying to tell you something. 😭
