💫 dvb_ringbuffer_reset(9) 💫

okay so this is a page straight out of the Kernel API Manual bestie, and it's about dvb_ringbuffer_reset — the little function that hits ctrl+z on your whole ringbuffer vibe. no cap, it's a short one but it eats. 🎀

---

✨ NAME ✨

dvb_ringbuffer_reset — resets the ringbuffer to initial state 🔄

---

🌸 SYNOPSIS 🌸

void dvb_ringbuffer_reset (struct dvb_ringbuffer *rbuf );

---

🦋 ARGUMENTS 🦋

• rbuf — pointer to struct dvb_ringbuffer 👉 that's literally the buffer you're about to reset, bestie

---

💅 DESCRIPTION 💅

So what does it actually do? Two things, and they're both iconic:

• Resets the read and write pointers to zero 🅾️
• Flushes the buffer 🚿

⚠️ and this is the part you cannot skip: this counts as a read and write operation. fr fr. it's not just vibes, it's a real read + a real write as far as the buffer's concerned. 🫶
