mei_irq_discard_msg(9)

💅 mei_irq_discard_msg(9) — like, the Kernel API Manual one 🎀

okay so bestie, welcome to mei_irq_discard_msg, a little function living its best life in the Kernel API Manual, and it does exactly one thing: it throws away a message you already received. that's it. that's the whole gig. and honestly? iconic. 🗑️✨

🌸 NAME 🌸

mei_irq_discard_msg — discard received message 💌➡️🚮

like, a message showed up, and we're not keeping it. bye. 🫶

---

✨ SYNOPSIS ✨

void mei_irq_discard_msg (struct mei_device *dev , struct mei_msg_hdr
*hdr , size_t discard_len );

so it returns void, meaning it hands nothing back — no return value, no little gift, not even a sticker. it just takes three things and gets to work. 💅

🦋 ARGUMENTS 🦋

• dev — the mei device 🌈 — this is the device we're working with, the main character of the whole mei situation.
• hdr — the message header 🎀 — you know, the header part of the message, the little label on the envelope.
• discard_len — the length of the message to discard (excluding header) 💀 — this is how much you're yeeting. and careful bestie, the header is not included in this number, so don't count it, or the numbers will be off and we'll be sad. 😭

reminder: discard_len = message length excluding the header. header stays out of the math. no cap. ✨
