✨ virtsnd_restore(9) ✨

okay so bestie, you know how this is page 9 of the kernel API manual? yeah. and we're talking about virtsnd_restore — the "resume device" girlie 🫶. like, it literally brings your virtio sound device back from its lil nap. she wakes up, she slays, she returns. 💅

---

🎀 SYNOPSIS 🎀

int virtsnd_restore (struct virtio_device *vdev );

that's the whole signature, no cap. one function, one argument, returns an int. iconic behaviour honestly ✨

---

🌸 ARGUMENTS 🌸

• vdev — the VirtIO parent device. that's it, that's the whole vibe. it's the parent device, she's the parent device 🦋

---

🧚 CONTEXT 🧚

any context 🔥 like genuinely any — no locks required, no special little situation, she's flexible like that. main character energy fr fr.

---

👑 RETURN 👑

• 0 when it works — success, we love to see it 💖
• -errno when it doesn't — yep, she throws you a negative errno and you deal with it 😭
