nvme_set_features_simple(2)

💖 nvme_set_features_simple(2) 💖

okay bestie, welcome to the libnvme API manual ✨ this one lives in section 2 of the manual, so it's a system/API call situation, and honestly? she's a little helper function and she knows it 💅

---

🌸 NAME 🌸

nvme_set_features_simple — the little helper function for @nvme_set_features() 🫶

like, she's not doing the whole job herself, she's the bestie that hands the main character their coffee before they go on stage ☕👑

---

✨ SYNOPSIS ✨

int nvme_set_features_simple (int fd , __u8 fid , __u32 nsid , __u32 cdw11 , bool save , __u32 *result );

that's the whole signature, no cap. she returns an int, and she takes a fd, a fid, an nsid, a cdw11, a save and a pointer to result 🎀

---

🦋 ARGUMENTS 🦋

• fd — the file descriptor of the nvme device 💻 this is your main character's backstage pass, you literally cannot get in without it.
• fid — the feature identifier 🏷️ which feature are we talking about? this is the name tag.
• nsid — the namespace ID, if applicable 🌈 sometimes it matters, sometimes it's like... not relevant bestie, and that's fine.
• cdw11 — the value you wanna set the feature to 🔥 this is the actual tea you're pouring in.
• save — save the value across power states 💾 yes queen, persist. she said "I will remember this even after a reboot."
• result — the command completion result from CQE dword0 📬 the little note that comes back to tell you how it went.

---

🌟 RETURN 🌟

so like, what does she give back? 👀

• the nvme command status if a response was received — peep enum nvme_status_field for the full menu of possibilities 📖
• or -1 with errno set if a response was not received 😭 yeah. it's giving "she didn't text back" energy.

ngl if you get the -1, go check errno immediately. it's not ghosting you, it's telling you something 💀

💜 SEE YOU LATER, BESTIE 💜
