🎀 libnvme_set_test_base_dir(9) 🎀

okay so bestie, this is the glow-up of the libnvme API manual page for libnvme_set_test_base_dir(9) — and it's literally about rerooting libnvme's on-disk files for testing. no cap, it's giving sandbox era 💅✨

🌸 NAME 🌸

libnvme_set_test_base_dir — reroot libnvme's on-disk files for testing 🫶

✨ SYNOPSIS ✨

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

🎀 ARGUMENTS 🎀

  • ctx — a struct libnvme_global_ctx object 👑
  • path — sandbox directory under /tmp, or NULL to restore defaults 🦋

💖 DESCRIPTION 💖

so basically this function redirects the files libnvme reads and writes — think the exclusion list, the ownership registry, ... — under path instead of their production locations, so a test can run against a throwaway directory. iconic behavior for test vibes, fr fr 😭✨

for safety, path must be confined to /tmp and contain no .. component; anything else is rejected. the vibe check is strict, bestie 🚨

passing NULL clears a previously set override. yes, it's the reset button for your sandbox era 💅

🌈 RETURN 🌈

  • 0 — success, slay 💖
  • -EINVAL — if ctx is NULL or path is not a valid sandbox path 🙈
  • -ENOMEM — on allocation failure 💀
