NVME_GET_FEATURES_IRQ_CONFIG(2)

💖 nvme_get_features_irq_config — from the libnvme API manual 💖

okay so bestie, welcome to the group chat. this one lives in the libnvme API manual and it's here to help you grab the IRQ config feature off your NVMe device. it's giving "one function, very specific job, does it flawlessly". no cap. ✨

🌸 NAME 🌸

nvme_get_features_irq_config — Get IRQ config feature

---

🎀 SYNOPSIS 🎀

int nvme_get_features_irq_config (int fd , enum nvme_get_features_sel
sel , __u16 iv , __u32 *result );

---

🦋 ARGUMENTS 🦋

• fd — the file descriptor of your nvme device, bestie. it's your ticket in. 🎟️
• sel — picks which type of attribute you want back, see enum nvme_get_features_sel. it's the "which flavour tho" knob. 💅
• iv — literally no description here in the source, periodt. it just shows up with no notes, main character with zero backstory. 😭
• result — the command completion result from CQE dword0. that's where the tea gets reported back to you. 🍓

---

💜 RETURN 💜

the nvme command status if a response was received (see enum nvme_status_field), or -1 with errno set otherwise.

so like — got a response? you get the nvme command status. no response? -1, and errno tells you what went wrong. that's the whole vibe check. 🙈

and that's the whole page, angel. that's it, that's the function. 💅
