NVME_INIT_GET_FEATURES_VOLTAGE_MEASUREMENT-LIBNVME3(2)

📦 version 3.2, in arch rolling

💅 nvme_init_get_features_voltage_measurement — like, the libnvme API manual but make it make sense ✨

okay bestie, so this one lives in the libnvme API manual and it's genuinely such a vibe once you get it. it's section 9, it's a function, and it's about getting a passthru command ready for Get Features – Voltage Measurement. yes, voltage. we're measuring it. slay. 🔥

🌸 NAME 🌸

nvme_init_get_features_voltage_measurement — initializes the passthru command for Get Features – Voltage Measurement. that's literally the whole job, and she does it well 🫶

🦋 SYNOPSIS 🦋

void nvme_init_get_features_voltage_measurement (struct
libnvme_passthru_cmd *cmd , enum nvme_get_features_sel sel , void *data
, __u32 len );

it's void, so she's not giving you anything back — she's setting things up for you. very generous of her honestly 💖

🎀 ARGUMENTS 🎀

  • cmd — the passthru command you're gonna use. this is the main character, the thing getting initialized 👑
  • sel — selects which type of attribute to return. it's an enum nvme_get_features_sel, so go look at that enum if you need the deets, iykyk ✨
  • data — the Start Voltage Measurements data buffer. this is where the good stuff goes. it's a struct nvme_voltage_measurement_start_data, so check that struct out too 🧚
  • len — length of data. a __u32. don't forget her, she matters 💅

🌈 DESCRIPTION 🌈

so what does she actually do? she initializes the passthru command buffer for the Get Features command, with the FID value set to NVME_FEAT_FID_VOLTAGE_MEASUREMENT. that's it. that's the whole thing. no cap.

like it's giving "setup era" — she's not running the command for you, she's just making sure the buffer is cute and ready so the command knows exactly what it's about. 🌸

heads up bestie: if you're confused about sel, data, or len, the answers are in enum nvme_get_features_sel and struct nvme_voltage_measurement_start_data. she's not gatekeeping, the types are right there 😌

and that's the whole page, bestie!! 🦋 this was the libnvme API manual, section 9, dated October 2026 — so like, go init some passthru commands and measure some voltage, periodt 💜✨
