bt_status(9)

💅 bt_status(9) — the Kernel API Manual glow-up ✨

okay so bestie, before we even get into it — this is a page from the Kernel API Manual and it's literally about translating your basic Unix mood into Bluetooth-speak. you're gonna slay this, i promise 🫶

---

🌸 NAME 🌸

bt_status — the standard errno value to Bluetooth error code translator, no cap 💖

---

✨ SYNOPSIS ✨

__u8 bt_status (int err );

---

🎀 ARGUMENTS 🎀

• err — the Unix/standard errno value you want converted. that's it, that's the whole vibe check 🦋

---

💖 DESCRIPTION 💖

so what this function does is it takes a standard/Unix errno value and converts it into the equivalent Bluetooth error code. it's giving translator bestie, it's giving bilingual icon 🔥

if the given errno isn't found — like, the function straight-up doesn't know her — then 0x1f gets returned by default, and that one's the "unspecified error" energy. very "idk her" of it, honestly 💀

and for err >= 0? no conversion is performed, the same value is immediately returned. no notes, no drama, she just hands it right back 🫶

---

⭐ RETURN ⭐

the Bluetooth error code. periodt 👑

🌈 SEE ALSO 🌈

this is the friend group, and honestly they're all iconic in their own way. first up, the kernel file:

• ./net/bluetooth/lib.c

and the whole squad of related calls:

• baswap(9)
• bt_to_errno(9)
• bt_info(9)
• bt_warn(9)
• bt_err(9)
• bt_dbg(9)
• bt_warn_ratelimited(9)
• bt_err_ratelimited(9)

iykyk, they all hang out in the same corner of the kernel 💜

lowkey remember: 0x1f is the default fallback for "errno not found" — that's the unspecified error, so don't be surprised when she shows up 🙈

alright bestie, that's the whole page. this gem lives over in ./net/bluetooth and the page is dated October 2026 — mwah, go forth and convert those errnos, you absolute main character 🧚‍♀️💅✨
