nvme_get_lo...ry_host_mcda(2)

✨ nvme_get_log_create_telemetry_host_mcda ✨

okay bestie, welcome to the libnvme API manual 💖 this one's a whole function and honestly? it's giving "short but mighty". grab a strawberry 🍓 and let's go.

---

🌸 NAME 🌸

nvme_get_log_create_telemetry_host_mcda — Create host telemetry log 🦋

like, it literally creates the host telemetry log. no cap.

---

🎀 SYNOPSIS 🎀

int nvme_get_log_create_telemetry_host_mcda (int fd , enum
nvme_telemetry_da mcda , struct nvme_telemetry_log *log );

she takes three things and gives you back an int. that's the whole vibe ✨

---

💅 ARGUMENTS 💅

• fd — File descriptor of nvme device 🔥 this is your ticket into the device, periodt.
• mcda — Maximum Created Data Area 👑 (yes, mcda is an acronym, the way that it ate)
• log — Userspace address of the log payload 🌈 where the log payload lives in userspace, aka your memory, not the kernel's.

---

🌟 RETURN 🌟

so here's what you get back, fr fr:

• The nvme command status if a response was received (peep enum nvme_status_field for the whole menu of statuses 👀)
• or -1 with errno set otherwise 😭 (the classic "something went sideways, go check errno" moment)

no guessing here bestie — one of those two, every single time. 💀

anyway that's the whole page, short and iconic. this was the libnvme API manual, dated July 2026 📅 — nvme_get_log_create_telemetry_nvme_get_lo...ry_host_mcda(2) if you're keeping receipts 🧾 slay, go create that telemetry log 💜✨🫶
