prepare_cell(9)

💅 NAME 💅

okay so bestie, welcome to prepare_cell(9) — that's the page, and the manual it lives in is the Kernel API Manual. And what does it do? It preps the cell ctrl and cmd in the current cell ✨ like it's getting the cell dressed for the function, fr fr.

---

🌸 SYNOPSIS 🌸

void prepare_cell (struct hinic_api_cmd_chain *chain , enum
hinic_node_id dest , void *cmd , u16 cmd_size );

heads up: it returns void, bestie — remember that, it's gonna come back in a sec 👀

---

🎀 ARGUMENTS 🎀

• chain — the chain for the command 🦋 like, this is the chain the command is riding on
• dest — the destination node on the card that will receive the command 💌 so we're literally addressing the envelope here
• cmd — the command data 📦 the actual payload, the main character
• cmd_size — the command size 📏 how big that payload is

---

✨ DESCRIPTION ✨

So the page says: Return 0 - Success, negative - Failure. 💀 That's the whole description, no cap — the synopsis says void and the description is out here talking about return values, and honestly? iykyk. Just take it exactly as written, bestie, don't @ me 🙈
