💅 nvme_init_set_features_timestamp(9) — libnvme API manual

okay bestie, gather round, because we're diving into the libnvme API manual and this one is genuinely such a little icon. it's nvme_init_set_features_timestamp, and yes the name is a mouthful but she serves. ✨

🎀 NAME 🎀

nvme_init_set_features_timestamp — initializes the passthru command for Timestamp. that's it, that's the whole gig. no cap. 🫶

✨ SYNOPSIS ✨

void nvme_init_set_features_timestamp (struct libnvme_passthru_cmd *cmd
, bool sv , __u64 tstmp , struct nvme_timestamp *ts );

look at her. four args, one void, zero drama. copy it exactly, bestie, don't get creative with the signatures, that's how you end up crying at 3am. 😭

💖 ARGUMENTS 💖

  • cmd — the passthru command you're gonna use. this is the vessel, the main character, the thing that gets filled in. 🫙
  • sv — Save value across power states. it's a bool, so it's giving yes/no energy. lowkey important, ngl.
  • tstmp — the current timestamp value you're assigning to this feature. it's a __u64, so she's a big girl. 🔥
  • ts — Timestamp data buffer — and here's the tea, this one gets populated by this function. you hand it over empty and she fills it in. iconic behavior honestly. 💅

🌸 DESCRIPTION 🌸

so what does she do? she initializes the passthru command buffer for the Set Features command, with FID value NVME_FEAT_FID_TIMESTAMP. periodt.

the important bit, and bestie I need you to actually hear me on this one: the caller must provide a valid buffer via ts, because this function is gonna populate it. if you pass garbage, you get garbage — that's not a vibe check you want to fail. 🙈

⚠️ real talk: ts must be a valid buffer. the function populates it, so it's not optional and it's not decorative. you've been warned, love you. 💀

🦋 SEE ALSO 🦋

there's nothing extra listed here bestie, this page is just her and her four arguments living her best life. 🌈

alright, that's the whole page! this masterpiece is from the libnvme API manual, dated October 2026 — shoutout to the libnvme girlies for keeping the docs cute. go populate that buffer, you absolute legend. 👑💜🍓
