clear_io_resources(9)

💅 clear_io_resources(9)

okay bestie, welcome to the Kernel API Manual, section 9 — yes we're in the kernel section, main character energy only 💖. This one's a huawei-hinic-flavored little function and it's honestly so simple you're gonna slay it.

---

✨ NAME ✨

clear_io_resources — sets the IO resources as not active in the NIC 🌸

Like, it's the "we're closing up shop" of IO resources. Being active is over, periodt.

---

🎀 SYNOPSIS 🎀

int clear_io_resources (struct hinic_hwdev *hwdev );

(Yes, the space before the closing paren is canon. Don't come for me, that's literally how it's written 🙈)

---

🦋 ARGUMENTS 🦋

• hwdev — the NIC HW device 💻✨

That's it. One argument. She's low maintenance, we love that for her.

---

💜 DESCRIPTION 💜

So what does it do? As the name says: IO resources → not active in the NIC. That's the vibe check.

And the return situation:

• 0 — Success 👑✅
• negative — Failure 😭💀

Heads up bestie: negative means it did not go well. Don't be out here treating a negative return like a win, fr fr.
