nvme_get_features_sel sel , __u32 *result );

like, literally the whole vibe in one signature. lowkey gorgeous. 💅

✨ ARGUMENTS ✨

• fd — the file descriptor of the nvme device 🦋 — this is your main character, the one you're actually talking to.
• nsid — namespace ID 🌸 — which namespace we're asking about, bestie, gotta be specific.
• sel — select which type of attribute to return, see enum nvme_get_features_sel 👑 — this is the vibe check for what kind of attribute comes back.
• result — the command completion result from CQE dword0 ⭐ — this is where the answer lands, so hand over a pointer and she'll fill it in.

✨ RETURN ✨

she returns the nvme command status if a response was received (peep enum nvme_status_field) 💜 … or -1 with errno set otherwise 😭.

so like, if it worked you get a status, and if it didn't you get -1 and errno is there to tell you what went down. always check errno, bestie, it's giving receipts. 🔥
