LIBNVME_CTRL_GET_QUEUE_COUNT-LIBNVME3(2)

📦 version 3.2, in arch rolling

💅 libnvme_ctrl_get_queue_count — get that queue_count, bestie

okay so this is from the libnvme API manual, section 9, and it's literally just one little getter function that goes and grabs the queue_count for you. tiny function, main character energy, no cap. 🎀

✨ NAME ✨

libnvme_ctrl_get_queue_count — get queue_count. that's it. that's the whole vibe. 💖

🌸 SYNOPSIS 🌸

int libnvme_ctrl_get_queue_count (const struct libnvme_ctrl *p ,
                                  const char **queue_count ,
                                  const char *dflt );

like, three args, one int back, we love a clean signature 🫶

🦋 ARGUMENTS 🦋

  • p — the struct libnvme_ctrl instance you're querying. this is your lil controller boo, const because we're just looking, not touching 🙈
  • queue_count — where to store the value on success. yes bestie, it's a const char **, so you hand over the address of your pointer and it fills it in for you ✨
  • dflt — the value to store in queue_count on failure. your emotional support fallback, the safety net, the "if it all goes wrong at least we have this" 🧚

🔥 RETURN 🔥

  • 0 — slay, success, it worked 💅
  • -ENOENT — the attribute does not exist. it's giving "not found", it's giving "she's not here" 💀
  • a negative errno — any other failure, so check your errno, iykyk 🌈
ngl bestie, check that return value. 0 is the only happy path here — everything else is a negative errno situation and you deserve to know about it before something confusing happens downstream. periodt.

⭐ that's the whole page, honestly. short and iconic 👑
