✨ mei_cldev_recv(9) ✨

okay so bestie, we're in the Kernel API Manual today and this one is called mei_cldev_recv — it's the client receive (read) situation. It's giving "please hand me the bytes, I'm waiting" energy. 🎀

🌸 SYNOPSIS 🌸

ssize_t mei_cldev_recv (struct mei_cl_device *cldev , u8 *buf , size_t
length );

literally that's it. three things in, one ssize_t out. no cap. 💅

🦋 ARGUMENTS 🦋

• cldev — the ME client device 💖 like, the device itself, the whole vibe you're receiving from
• buf — the buffer that's gonna receive the data 🫶 pops the bytes in here
• length — how long that buffer is 🌸 keep it honest, bestie, this is your size limit

⭐ RETURN ⭐

it returns the read size in bytes — as the page puts it, read size in bytes of < 0 on error 😭 so yeah: you get a byte count when things are slay, and anything < 0 means error, no cap. check it. always check it. 🔥

👑 SEE ALSO 👑

the kernel file is ./drivers/misc/mei/bus.c and honestly the whole friend group is tagged in this one — here's every single one, and yes I mean every single one, because we do not leave anyone out in this house 🫶✨
