💅 nvme_init_identify_csi_ns_user_data_format(9) — the libnvme API manual, but make it make sense 🦋

okay so bestie, welcome to the libnvme API manual, section 9, and today's main character is nvme_init_identify_csi_ns_user_data_format — yes that whole thing, it's giving "my parents named me after the wifi password" but she's iconic and she knows it 💖

✨ NAME ✨

nvme_init_identify_csi_ns_user_data_format — sets up the passthru command for the Identify namespace user data format. that's it, that's the vibe 🎀

🌸 SYNOPSIS 🌸

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

no return value, no drama, she just does the thing and leaves 😌✨

🧚 ARGUMENTS 🧚

• cmd — the command data structure you're initializing, like yes we're filling her in, she's getting the full glow-up 💅
• csi — the Command Set Identifier, this is literally the CSI of the NVMe world, no cap 🔍
• fidx — the Format Index, __u16, she's a whole sixteen bits of "which format bestie" ✨
• uidx — the UUID selection, if supported, __u8, small but mighty 🫶
• data — your user space destination address where the data gets transferred, aka where the tea lands 🍓

🔥 DESCRIPTION 🔥

so what she actually does: she initializes the passthru command buffer for the Identify command, with the CNS value set to NVME_IDENTIFY_CNS_CSI_NS_USER_DATA_FORMAT 👑

that's the whole job. lowkey efficient. highkey slay. the passthru command buffer gets its setup, the CNS value gets set, everyone goes home happy 🌈

ngl this one's a one-trick pony and that trick is very specific — but she does it perfectly, periodt 💜
