libnvme_ctrl_get_phy_slot(9)

💅 libnvme_ctrl_get_phy_slot — the one where you grab the phy_slot

okay so this is a page from the libnvme API manual, and bestie, it's a tiny one but she's iconic. We're getting the phy_slot. That's it. That's the whole vibe. 🦋

✨ SYNOPSIS ✨

int libnvme_ctrl_get_phy_slot (const struct libnvme_ctrl *p , const char
**phy_slot , const char *dflt );

like, yes, that's the whole call. three args, one int back. slay. 💅

🎀 ARGUMENTS 🎀

• p — the struct libnvme_ctrl instance you're querying. this is your main character — the controller you're asking about. 👑
• phy_slot — where the value gets stored on success. it's a const char **, so like... you're handing over a pointer to a pointer and trusting the function to fill it in. no pressure. 🫶
• dflt — the value to store in phy_slot on failure. so if things go sideways, you still get something in there — your little safety net. 🌸

⭐ RETURN ⭐

• 0 — success, we ate. ✅
• -ENOENT — the attribute does not exist. it's giving "sorry bestie, that field isn't here." 😭
• a negative errno — on failure. any other bad news shows up as a negative errno, so like, check your return value, fr fr. 💀

ngl the return value is doing a lot of work here: 0 good, -ENOENT means no such attribute, and anything else negative is just "errno things happened." don't skip the check, i'm begging. 🙈

okay that's literally the whole page, she's short but she's efficient, and honestly? obsessed. 🧚

sign-off time: this little beauty comes from the libnvme API manual, dated October 2026 — and yeah, the original footer has a goofy duplicated libnvme_ctrl_get_phy_slolibnvme_ctrl_get_phy_slot(9) situation going on at the end of it (not me noticing that 💀), so consider it lovingly preserved in spirit. bye bestie, go get that phy_slot! 🍓💜🔥
