💅 cbus_send_data(9) — Kernel API Manual

okay bestie, so this is cbus_send_data, straight out of the kernel API manual — yes, the kernel has its own manual pages, we love a documented kernel 👑

---

✨ NAME ✨

cbus_send_data — sends @len amount of data over the bus 🚌💨

Like. That's the whole job. It puts @len worth of data onto the bus. Iconic, minimal, does exactly what it says on the tin.

---

🌸 SYNOPSIS 🌸

void cbus_send_data (struct cbus_host *host , unsigned data , unsigned
len );

ngl the spacing around those commas is giving "written at 3am by a kernel dev", but we reproduce it faithfully because that's the assignment 🫶

---

🦋 ARGUMENTS 🦋

• host — the host we're using 💖 like, which bus host this transfer is riding on, that's the one, main character energy.
• data — the data to send ✨ the actual payload, the moment we've all been waiting for.
• len — size of the transfer 🎀 how much of it we're sending, the vibe check on the byte count.
