copy_data(9)

💖 copy_data(9) — like, the Kernel API Manual's own little data-copying icon 💖

okay so bestie, we're in the Kernel API Manual today and this one is a whole function. it's copy_data(9) and honestly? she does exactly what it says on the tin 🎀

---

✨ NAME ✨

copy_data — implements data copying function

like yes that's the whole name, she said what she said 💅

---

🌸 SYNOPSIS 🌸

bool copy_data (struct channel *channel , struct mbo *mbo );

that's the whole signature, copy it exactly, no cap 🫶

---

🦋 ARGUMENTS 🦋

• channel — a channel. that's it. that's the whole description. a channel 🎀
• mbo — the MBO from core ⭐ (yes, capital-M-B-O, from core, that's what the manpage says, iykyk)

---

💜 DESCRIPTION 💜

okay so here's the vibe: copy_data copies data from/to the ring buffer to/from the MBO, and then it updates the buffer position. that's the entire job. she's a one-task queen and she ate 👑

lowkey iconic that the description is one line and doesn't need more. she's efficient like that ✨

• get_channel(9)
• playback_thread(9)
• pcm_open(9)
• pcm_close(9)

and that's the whole page!! source is ./drivers/most, version/date is October 2026, and the manpage is copy_data(9) — mwah, go read the SEE ALSO list, i'm obsessed with you for making it this far 💖🎀🦋✨
