libie_ctlq_tx_desc_from_msg(9)

💅 libie_ctlq_tx_desc_from_msg(9) — kernel API manual, but make it cute

okay so bestie, welcome to the Kernel API Manual ✨ this one's about libie_ctlq_tx_desc_from_msg(9) and honestly? it's a little glue function and it ate. no cap.

---

🌸 NAME 🌸

libie_ctlq_tx_desc_from_msg — initialize a Tx descriptor from a message 💌

like, you got a message, you got a descriptor, and this function makes the descriptor be that message. matchmaker energy fr fr.

---

✨ SYNOPSIS ✨

void libie_ctlq_tx_desc_from_msg (struct libie_ctlq_desc *desc ,
                                  const struct libie_ctlq_msg *msg );

it returns void, so don't go looking for a return value, there isn't one, that's not the vibe 💀 it's just void and const-respecting and living its life.

---

🎀 ARGUMENTS 🎀

• desc — the descriptor to be initialized 🫶 this is the one getting set up, the main character of the operation.
• msg — a filled control queue message 💖 yep, "filled" — it's already got its stuff in it, and it's const so nobody's touching it.

so you hand it a descriptor and a message, and the descriptor gets initialized from that message. iconic behavior honestly.
