libnvme_get_telemetry_max(9)

📦 version 3.2, in arch rolling

🌸 libnvme_get_telemetry_max(9) 🌸

okay so bestie, welcome to the libnvme API manual — yes that's the whole manual name, she's a whole vibe. this page is all about libnvme_get_telemetry_max, and honestly? it's giving "small function, big responsibility." let's get into it 💅

✨ NAME ✨

libnvme_get_telemetry_max — Get telemetry limits 🎀

like, the limits of your telemetry. the ceiling. the cap. the "no ma'am, you cannot go bigger than this" energy. 🔥

🦋 SYNOPSIS 🦋

int libnvme_get_telemetry_max (struct libnvme_transport_handle *hdl ,
enum nvme_telemetry_da *da , size_t *max_data_tx );

periodt. that's the whole call. three args, one int coming back at you. 🫶

💖 ARGUMENTS 💖

  • hdl — Transport handle. literally the thing that tells the function how it's talking to the controller. main character energy, no cap. 👑
  • da — On success return max supported data area. so like, when it works, this pointer gets filled in with the biggest data area you can have. slay. ✨
  • max_data_tx — On success set to max transfer chunk supported by the controller. the controller has opinions about chunk size and this is where you find out what they are. 🙈
ngl bestie: both da and max_data_tx only get their values on success. if it fails, don't go reading them like they mean something, okay? 💀

🌈 RETURN 🌈

so what comes back? three possible flavors:

  • 0 on success — iconic, we love a clean win 🎉
  • the nvme command status if a response was received (see enum nvme_status_field) — like, the controller did answer, it just answered with attitude. go check that enum iykyk 🧚
  • a negative error otherwise — the "something went sideways before we even got a response" situation 😭

⭐ a lil sign-off ⭐

this page is from the libnvme API manual, dated October 2026, and it's officially libnvme_get_telemetry_max(9) — go forth and get those telemetry limits, bestie. you're gonna ate. 💜🎀🦋
