libnvmf_registry_retrieve(9)

📦 version 3.2, in arch rolling

💅 libnvmf_registry_retrieve — read an attribute from a controller's registry entry 💅

Okay bestie, so this is a page from the libnvme API manual (section 9, kernel/API vibes), and it's about one very specific little function that goes and fetches a single attribute out of a controller's registry entry. Like reaching into someone's bag and grabbing exactly one thing. Iconic behavior, honestly. 🎀

✨ NAME ✨

libnvmf_registry_retrieve — Read an attribute from a controller's registry entry

🦋 SYNOPSIS 🦋

int libnvmf_registry_retrieve (struct libnvme_global_ctx *ctx , const
char *device , const char *attr , char **value );

🌸 ARGUMENTS 🌸

  • ctx — the libnvme global context, and she must not be NULL, periodt. No context, no service. 🙈
  • device — the kernel device name, like "nvme3" for example. That's your target, bestie. 🎯
  • attr — the attribute name you wanna retrieve, e.g. "owner". Pick your fave. 💅
  • value — on success, this gets set to a newly allocated string holding the attribute value. And listen: the caller must free this string. Not me letting you leak memory, ngl. Free it. 😭

💜 RETURN 💜

  • 0 on success — slay, you got it ✨
  • -ENOENT if the controller is not registered or the attribute isn't present — basically a no-show 🫶
  • -ENOMEM if allocation fails — the malloc said nah 💀
  • otherwise, a negative errno from the underlying system calls. Underlying syscalls said what they said. 🌈
Heads up bestie: that value string is yours to free. The function allocates it, you clean it up. That's the deal. 🧚

⭐ SIGN-OFF ⭐
