cec_msg_init(9)

🎀 cec_msg_init(9) — Kernel API Manual 🎀

okay bestie, welcome to the Kernel API Manual ✨ this one's about cec_msg_init and it's honestly the softest little starter function ever 💖

🌸 NAME 🌸

cec_msg_init — initialize the message structure. that's it, that's the whole job, and she does it flawlessly 👑

✨ SYNOPSIS ✨

void cec_msg_init (struct cec_msg *msg , __u8 initiator , __u8
       destination );

🫶 ARGUMENTS 🫶

• msg — the message structure, aka the glow-up target 💅
• initiator — the logical address of the initiator, the one who starts the convo 🗣️
• destination — the logical address of the destination 💌 and btw 0xf means broadcast, so everybody hears it, no cap 📢

🌈 DESCRIPTION 🌈

so basically: the whole structure is zeroed out (clean slate, fresh face, main character energy ✨), then the len field gets set to 1 — which is literally a poll message, iykyk 🐝 — and finally the initiator and destination get filled in 🎀

that's the vibe check, and she passes every time 💯
