nbd_aio_is_closed(3)

✨ nbd_aio_is_closed ✨

okay so bestie, welcome to the libnbd girlies club 💅 this one's a nbd_aio_is_closed(3) situation — that's the page, that's from the LIBNBD manual, and yes we are absolutely reading the whole thing together 🫶

---

🌸 NAME 🌸

nbd_aio_is_closed — literally just checks whether the connection is closed, no cap 💀

---

🎀 SYNOPSIS 🎀

#include <libnbd.h>

int nbd_aio_is_closed (
      struct nbd_handle *h
    );

---

🦋 DESCRIPTION 🦋

So the whole vibe here: this function returns true if the connection has closed. That's it. That's the gig ✨

But listen — there is no way to reconnect a closed connection. Not a secret trick, not a workaround, nothing 🙈 instead you have to close the whole handle. Like, the entire thing. It's giving "burn it down and start over" energy, and honestly? iconic.

---

🌈 RETURN VALUE 🌈

This call returns a boolean value. yep, true or false, that's the whole menu 🍓

---

💜 ERRORS 💜

Good news bestie: this function does not fail. zero drama, zero tears, we love that for us 😌

The one thing though — the following parameters must not be NULL: "h". For more info go peek at "Non-NULL parameters" in libnbd(3) 📖

---

⭐ VERSION ⭐

This function first appeared in libnbd 1.0 🎉 so it's lowkey an OG.

If you need to test whether this function is available at compile time, check whether the following macro is defined:

#define LIBNBD_HAVE_NBD_AIO_IS_CLOSED 1
