πŸ“¦ version 3.2, in arch rolling

πŸ’… nvme_init_id..._data_format(9) β€” libnvme API manual, bestie edition

okay so real talk, this is a page from the libnvme API manual, section 9. Yes section 9, we love a deep-cut section. Let's get into it ✨


🌸 NAME 🌸

nvme_init_identify_ns_user_data_format β€” sets up the passthru command for the Identify namespace user data format thing. That's the whole vibe. πŸŽ€


πŸ¦‹ SYNOPSIS πŸ¦‹

void nvme_init_identify_ns_user_data_format (struct libnvme_passthru_cmd
*cmd , enum nvme_csi csi , __u16 fidx , __u8 uidx , void *data );

it returns void btw, so like… no return value, no drama, she just does the thing and leaves πŸ’…


✨ ARGUMENTS ✨

  • cmd β€” the command data structure you're initializing. this is the main character, she's getting set up 🫢
  • csi β€” the Command Set Identifier. it's an enum nvme_csi, iconic enum behavior πŸ‘‘
  • fidx β€” the Format Index. it's a __u16, so she's got room πŸ“
  • uidx β€” the UUID selection, if supported. key words: if supported, bestie, don't come for me πŸ™ˆ
  • data β€” the user space destination address where the data gets transferred. that's where the goods go πŸ“¦

πŸ”₯ DESCRIPTION πŸ”₯

so what does she actually do? she initializes the passthru command buffer for the Identify command, with the CNS value set to NVME_IDENTIFY_CNS_NS_USER_DATA_FORMAT. that's it. that's the whole job. no cap. ⭐

ngl, this one's short and sweet β€” no warnings, no deprecated nonsense, no scary undefined behavior. just a clean little init function doing exactly what it says on the tin. we love a low-drama libnvme call πŸ’–

🧚 the cute sign-off 🧚

this little beauty comes to you from the libnvme source, dated October 2026 β€” go off, future release 🌈. mwah, hope your passthru buffers are always initialized correctly, bestie πŸ’œπŸ’…
