libnvme_set_etdas(9)

💅 libnvme_set_etdas — bestie's guide to the ETDAS bit 🦋

okay so this is a page straight out of the libnvme API manual ✨ and it's genuinely so simple you're gonna slay it. Like, the whole deal is: this function flips the Extended Telemetry Data Area 4 Supported bit. That's it. That's the whole vibe. 🎀

✨ NAME ✨

libnvme_set_etdas — Set the Extended Telemetry Data Area 4 Supported bit 👑

like yes, that's the actual name of the bit, no cap. Extended Telemetry Data Area 4. Supported. She's long but she's iconic. 💜

---

🌸 SYNOPSIS 🌸

int libnvme_set_etdas (struct libnvme_transport_handle *hdl , bool *changed );

literally just two things, bestie — a handle and a bool pointer. we love a low-argument function fr fr 🫶

---

🦋 ARGUMENTS 🦋

• hdl — the transport handle 💫 — like, the thing you're talking through. you bring your own, this function does not make one for you, iykyk.
• changed — a bool that's there to tell you whether or not the host behavior support feature had been changed 🙈 — so it's not just a yes/no answer outta nowhere, it's reporting back on that specific feature. keep an eye on her.

---

⭐ RETURN ⭐

so what comes back? two possible situations, and you gotta know which one you're in:

• if a response was actually received, you get the nvme command status 💅 (and yeah, that's the kind documented over in enum nvme_status_field — go look, she's right there)
• otherwise, you get a negative error code 💀

no in-between, no vibes-based guessing. check your return value, bestie, always. 🔥

ngl this is the part people skip and then act surprised when stuff breaks. don't be that girl. do the error check. 🫶

and that's the whole page!! short, sweet, and honestly kind of a main character for such a tiny function 🌈

sign-off szn 🎀 — this came from the libnvme API manual, dated October 2026, and yes she's still serving the same energy as libnvme_set_etdas(9). mwah 💋
