NVME_GET_LOG_CHANGED_ALLOC_NS_LIST(2)

πŸ’– nvme_get_log_changed_alloc_ns_list β€” bestie's guide to the Changed Allocated Namespace List Log πŸ’–

okay so real talk, this is one of those libnvme man pages (it lives in section 2 of the manual, the API-call girlies section πŸŽ€), and it's genuinely so useful. Sit down, grab a strawberry drink πŸ“, and let's get into it.


✨ NAME ✨

nvme_get_log_changed_alloc_ns_list β€” Retrieve Changed Allocated Namespace List Log

Like, the whole point of her: she goes and fetches you the log page that tells you which namespaces have had their allocated status change. That's it, that's the girl. πŸ‘‘


🌈 SYNOPSIS 🌈

int nvme_get_log_changed_alloc_ns_list (int fd , bool rae , __u32 len ,
       struct nvme_ns_list *log );

no cap, that's the whole signature. four things go in, one int comes back out. πŸ’…


πŸ¦‹ ARGUMENTS πŸ¦‹

  • fd β€” File descriptor of nvme device. literally the handle to the device you're talking to, nothing more, nothing less. πŸ”₯
  • rae β€” Retain asynchronous events. this is the bool that says "bestie, keep the async events, don't clear them". πŸ‘€
  • len β€” The allocated length of the log page. as in, how much room you actually gave her to write into. respect the buffer, fr fr. πŸ“
  • log β€” User address to store the log page. this is your memory, you're handing her the address, and she will fill it. struct nvme_ns_list *, exactly as promised. 🫢

πŸ’€ RETURN πŸ’€

She gives you back the nvme command status if a response was received (peep enum nvme_status_field for what those statuses mean, iykyk), or -1 with errno set otherwise.

so if you get a -1, that's not a vibe, that's an error β€” go check errno, she always leaves a note. 😭

that's genuinely the whole page, bestie. no hidden options, no secret flags, just four args and a return value. short queen behavior honestly. ✨


okay and for the cute sign-off: this page comes from the libnvme API manual (that's the source, the version vibe) and it's dated July 2026. mwah, go forth and read your namespace lists. πŸ’–πŸŒŸπŸŽ€
