nvme_zns_identify_ns(2)

✨ nvme_zns_identify_ns — ZNS identify namespace data ✨

okay bestie, gather round 🫶 this one lives in the libnvme API manual, and it's a section 2 situation, so it's a syscall-flavoured little guy: nvme_zns_identify_ns. It's giving "ask the namespace who it is" and honestly? iconic.

🎀 SYNOPSIS 🎀

int nvme_zns_identify_ns (int fd , __u32 nsid , struct nvme_zns_id_ns *data );

three lil inputs, one int coming back at you. no cap.

🌸 ARGUMENTS 🌸

• fd — the file descriptor of your nvme device. this is your lil entry pass into the device, so have it open and ready 💅
• nsid — the namespace you wanna identify. like, which one bestie, be specific 🌈
• data — user space destination address where the data gets transferred to. it's the lil basket you're carrying the answer home in 🎀

💖 RETURN 💖

So here's the tea on what you get back ☕: you get the nvme command status if a response was actually received — peek at enum nvme_status_field for the whole menu of possibilities, iykyk.

If not? It's -1 and errno is set instead. so like, check your errno, don't just sit there staring at the -1 😭
