💖 NOZZLE_CLOSE(3) 💖

okay bestie, welcome to the Kronosnet Programmer's Manual ✨ this one's short and sweet and honestly iconic for it — it's the page that teaches you how to say goodbye to a nozzle device. no cap.

🌸 NAME 🌸

nozzle_close — deconfigure and destroy a nozzle device 🫶

like... it's the cleanup girlie. the one who turns off the lights and locks the door.

---

✨ SYNOPSIS ✨

#include <libnozzle.h>

int nozzle_close(
    nozzle_t  nozzle
);

that's it. one arg. one int. we love a low-effort slay 💅

🦋 DESCRIPTION 🦋

nozzle_close

• nozzle — pointer to the nozzle struct to destroy 💀 like, genuinely destroy it. this is the part where the nozzle device gets deconfigured AND destroyed, so don't come for me when it's gone.

lowkey important: you're handing over a pointer to the struct and the function is gonna tear it down. that's the whole vibe. it's giving "main character exits stage left" 🌈

🎀 RETURN VALUE 🎀

• 0 — success, we ate, no crumbs 👑
• -1 — error, and errno is set 😭 so go check your errno, bestie, it's trying to tell you something
