💖 heci_hcbww_write(9) — Kernel API Manual, but make it cute 💖

okay so bestie, welcome to the heci_hcbww_write(9) page. This is the one where we write 32bit data to the host circular buffer. That's the whole plot. No cap. The manual name is literally right there in the title because we're keeping it close and letting it have main character energy. 💅

🌸 NAME 🌸

heci_hcbww_write — write 32bit data to the host circular buffer.

✨ SYNOPSIS ✨

void heci_hcbww_write (const struct issei_heci_hw *hw , u32 data );

It's giving void, so no return value is coming back — this function is just here to do the write and exit stage left. 🫶

🎀 ARGUMENTS 🎀

• hw — the heci hardware structure 💖
• data — the 32bit data to be written to the host circular buffer ✨

lowkey, these two are the whole cast: the hardware structure and the 32bit data headed for the host circular buffer. 🦋
