💅 libnvme_set_test_sysfs_dir — libnvme API manual, bestie edition

Okay so picture this: you're deep in the libnvme source (iconic of you), and you need to point libnvme's sysfs lookup at some other directory. Not the real one. A test one. A little fake sysfs sandbox, if you will 🧚. That's literally exactly what this function is for. Welcome to the libnvme API manual, October 2026 edition, no cap.

✨ NAME ✨

libnvme_set_test_sysfs_dir — set libnvme's lookup sysfs path for testing 🎀

Like, it overrides where libnvme goes looking for sysfs. For testing. That's the whole vibe.

🌸 SYNOPSIS 🌸

int libnvme_set_test_sysfs_dir (struct libnvme_global_ctx *ctx , const
char *path );

Yes the line break is real, that's just how it's typeset, don't come for me 😭. It takes your ctx and your path and returns an int. Simple. Clean. Slay.

🦋 ARGUMENTS 🦋

  • ctx — your struct libnvme_global_ctx object 👑. The main character, honestly. It's the context everything hangs off of.
  • path — the directory that has sysfs in it 🍓. Or, and this is the important part bestie, you can pass NULL here to restore the defaults — i.e. snap everything back to normal, no test path, back to the real deal. Very "not me forgetting to reset my test dir" energy 🙈.

💜 RETURN 💜

  • 0 on success — we love a clean win ✨
  • -EINVAL if ctx is NULL 💀 — like, you gotta give it a context, babe, it can't read your mind
  • -ENOMEM on allocation failure 😭 — the memory said no
fr fr, check that return value. -EINVAL and -ENOMEM are both out here waiting to humble you.

And that's the whole page, bestie 🫶. Short and sweet — a rare gift from the manpage gods. This lil beauty comes to you straight from the libnvme API manual, dated October 2026 (and yeah, the footer's version tag is a whole mouthful, libnvme_set_test_sysfs_libnvme_set_test_sysfs_dir(9), which is giving "my wifi password" but make it documentation 🌈⭐). Now go set that test sysfs dir and remember to set it back to NULL after, iykyk 💅🔥.
