nbd_connection_state(3)

💅 nbd_connection_state(3) — libnbd's lil vibes check

okay so bestie, welcome to nbd_connection_state from the libnbd family 🦋 this one's literally just "hey, what's the connection doing rn?" and honestly it's giving main character energy for debugging ✨

---

🌸 NAME 🌸

nbd_connection_state — returns a string describing the state of the connection 🎀

---

✨ SYNOPSIS ✨

#include <libnbd.h>

const char * nbd_connection_state (
               struct nbd_handle *h
             );

bestie just hand it your struct nbd_handle *h and it hands you back a const char *, slay 💅

---

🦋 DESCRIPTION 🦋

So like, this returns a descriptive string for the state of the connection. That's it, that's the whole vibe 🔥

It's perfect for debugging or troubleshooting, ngl — but do NOT rely on the state of connections because it may change in future versions 😭 like, it's not a promise, it's a peek, yk?

💀 real talk: this is a debugging tool, not an API contract. don't build your whole personality around it.

---

🎀 RETURN VALUE 🎀

This call returns a statically allocated string — and the way it stays valid for the lifetime of the process, or until libnbd is unloaded by dlclose(3), is honestly iconic 👑

You must not try to free the string. Periodt. It's not yours, don't touch it 🙈

---

💀 ERRORS 💀

On error, NULL is returned. that's the whole thing, no cap 🫶

Refer to "ERROR HANDLING" in libnbd(3) for how to get further details of the error — iykyk, that's where the lore lives 📖

Also! The following parameters must not be NULL: h. For more info, see "Non-NULL parameters" in libnbd(3) 😤 like fr fr, hand it a real handle.

---

⭐ VERSION ⭐

This function first appeared in libnbd 1.0 — an OG, a legend, we stan 💖

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

#define LIBNBD_HAVE_NBD_CONNECTION_STATE 1

lowkey the cleanest vibe check there is ✅
