nvme_set_fe...ance_evt_cfg(2)

💖 nvme_set_features_endurance_evt_cfg — a libnvme API manual moment 💖

okay bestie, welcome to the nvme_set_fe...ance_evt_cfg(2) page from the libnvme API manual. this one's short and sweet and honestly? she's giving "tiny function, big responsibility" energy. let's get into it 🎀

---

✨ NAME ✨

nvme_set_features_endurance_evt_cfg — Set endurance event config feature

that's it. that's the whole name. slay. 💅

---

🌸 SYNOPSIS 🌸

int nvme_set_features_endurance_evt_cfg (int fd , __u16 endgid , __u8
egwarn , bool save , __u32 *result );

five args, one int coming back at you. it's giving "get in, configure your endurance warnings, get out" 🦋

---

🫶 ARGUMENTS 🫶

bestie every single one of these matters, so here we go, no skipping:

• fd — File descriptor of nvme device. this is your lil hall pass to the drive itself, don't lose it 🔑
• endgid — Endurance Group Identifier. it's telling the function which endurance group we're talking about, so be specific, she's not a mind reader 💜
• egwarn — Flags to enable warning, see enum nvme_eg_critical_warning_flags. so this is where you set your warning config, and the enum nvme_eg_critical_warning_flags is your bestie that has all the actual flag values. go look at her, she's got the deets 👑
• save — Save value across power states. true means it sticks around after a power cycle, so like… she remembers you. iconic behavior fr fr ✨
• result — The command completion result from CQE dword0. this is a pointer, so the answer gets written into whatever __u32 you point it at. lowkey the receipts 📩

---

💀 RETURN 💀

The nvme command status if a response was received (see enum nvme_status_field) or -1 with errno set otherwise.

so basically: you get a real status back if the drive answered you, and you go check enum nvme_status_field to decode what she said. if things went fully sideways and nobody responded, it's -1 and errno is your emotional support error variable 😭 do not ignore errno, she's trying to tell you something.

👑 a lil sign-off 👑

no cap, that's the whole page. this vibe check was brought to you by the libnvme API manual, dated July 2026, and this section (section 2, the syscalls girlies) says bye bestie — go set some endurance event config, you got this 💜🦋✨🎀
