NVME_INIT_SET_FEATURES_CTRL_METADATA-LIBNVME3(2)

💅 nvme_init_set_features_ctrl_metadata(9) — libnvme API manual 🎀

okay bestie, welcome to the libnvme API manual, we're doing the nvme_init_set_features_ctrl_metadata page today and honestly it's short, sweet, and ate ✨

---

🌸 NAME 🌸

nvme_init_set_features_ctrl_metadata — Initialize passthru command for Controller Metadata 🫶

---

🦋 SYNOPSIS 🦋

void nvme_init_set_features_ctrl_metadata (struct libnvme_passthru_cmd
*cmd , bool sv , __u8 ea , struct nvme_host_metadata *data );

no cap, that's the whole signature. void return, so nothing comes back at you 💀

---

⭐ ARGUMENTS ⭐

• cmd — the Passthru command you're gonna use 💖 this is the buffer getting set up, so hand it over already allocated
• sv — Save value across power states, yes queen, bool, your call 🔥
• ea — Element Action (EA), and bestie it's literally __u8 — see enum nvme_host_metadata_ea for the actual values 👑
• data — Host Metadata data buffer, and it's a struct nvme_host_metadata pointer, see struct nvme_host_metadata for what goes in there 🎀

---

✨ DESCRIPTION ✨

So what does this actually do? It initializes the passthru command buffer for the Set Features command, with the FID value NVME_FEAT_FID_CTRL_METADATA 🦋 that's it. that's the vibe. it's giving setup-function main character energy — all the plumbing, no drama 💅

lowkey important: it's Controller Metadata here, not the other flavors, and the FID is literally NVME_FEAT_FID_CTRL_METADATA, so don't go swapping it, iykyk 🙈

and that's the whole page bestie, go forth and set those features 🌈💜
