nbd_set_handle_name(3)

✨ nbd_set_handle_name(3) ✨

okay bestie, so this is a page from the LIBNBD manual — yes, the libnbd(3) girlies — and it's about giving your NBD handle a cute little name 🎀 like it's a pet or a group chat nickname. let's get into it 💅

---

🌸 NAME 🌸

nbd_set_handle_name — set the handle name 🏷️

---

🦋 SYNOPSIS 🦋

#include <libnbd.h>

int nbd_set_handle_name (
      struct nbd_handle *h, const char *handle_name
    );

---

💖 DESCRIPTION 💖

so every handle has a name, right? and that name is unique within the current process — no dupes allowed, it's giving main character energy only 👑. the handle name is what shows up in debug output.

normally these names just generate themselves automatically, and they look like "nbd1", "nbd2", etc. — fully autopilot, no thoughts head empty 🫶. but you can optionally use this call to hand your handle a name that's actually meaningful for your application, which makes the debugging output wayyy easier to understand. it's the difference between "who is nbd7" and "oh that's my storage connection, slay" 💀✨

---

⭐ RETURN VALUE ⭐

if the call goes well, the function returns 0. iconic, no notes 💚

---

🔥 ERRORS 🔥

on error, -1 is returned. 😭

for the deets on how to get further details of the error, go look at "ERROR HANDLING" in libnbd(3) — it's all laid out there, iykyk.

also!! important: the following parameters must not be NULL: "h", "handle_name". for more info see "Non-NULL parameters" in libnbd(3). don't be out here passing NULLs, bestie, that's not the vibe 🙈

---

🧚 VERSION 🧚

this function first appeared in libnbd 1.0 — an OG fr fr ⭐

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