KNET_HAN...VE_DATAFD(3)

🦋 knet_handle_remove_datafd — bestie, let's unplug that fd 💅

okay so real talk, this is a page from the Kronosnet Programmer's Manual (yes, the kronosnet girlies stay winning) and it's about exactly one function that does exactly one thing. no cap. 🎀

---

✨ NAME ✨

knet_handle_remove_datafd — remove a file descriptor from knet. that's it. that's the whole vibe. 🫶

---

✨ SYNOPSIS ✨

#include <libknet.h>

int knet_handle_remove_datafd(
    knet_handle_t  knet_h,
    int            datafd
);

look at her. so demure. so mindful. 🧚

---

✨ DESCRIPTION ✨

knet_handle_remove_datafd — the function herself, the main character, the moment. 👑

• knet_h — pointer to knet_handle_t. that's your handle bestie, the whole connection situation.
• datafd — the file descriptor to remove. NOTE that if the socket/fd was created by knet_handle_add_datafd, the socket will be closed by libknet. 👀

okay so like, read that note twice fr fr. if knet made that fd, knet is gonna close it for you. you don't gotta do it yourself. don't double-close, that's giving chaos energy and we don't do that here. 😭

---

✨ RETURN VALUE ✨

knet_handle_remove_datafd returns 0 on success, -1 on error, and errno is set. slay when it's 0, cry when it's -1. check that errno bestie, she's telling you the tea. 💖
