💖 mei_cldev_recv_timeout(9) — the kernel API manual, bestie edition 💖

okay so this is a page straight out of the kernel API manual (kernel docs, but make it cute), and it's all about mei_cldev_recv_timeout — the client receive-with-timeout read. yes the name is a mouthful. no we're not renaming it. let's go 🫶

✨ NAME ✨

mei_cldev_recv_timeout — client receive with timeout (read). that's it, that's the vibe. it reads. it has a timeout. iconic behavior honestly 💅

🦋 SYNOPSIS 🦋

ssize_t mei_cldev_recv_timeout (struct mei_cl_device *cldev , u8 *buf ,
       size_t length , unsigned long timeout );

look at that signature. four args, one return, zero chill. slay ✨

🎀 ARGUMENTS 🎀

  • cldev — me client device. your main character device, the one you're reading from 🧚
  • buf — buffer to receive. this is where the bytes land. keep it cozy.
  • length — buffer length. how much room you're giving it. don't be stingy.
  • timeout — send timeout in milliseconds, 0 for infinite timeout. yes, 0 means wait forever. no cap. choose wisely 🙈
lowkey note: the doc says "send timeout" even though this is the receive function — that's literally what the original says, so we're keeping it fr fr. no editing the lore 💀

🔥 RETURN 🔥

  • read size in bytes — the good ending 🎉
  • < 0 on error — the not-so-good ending 😭

that's the whole return section, bestie. very demure, very mindful.

⭐ SEE ALSO ⭐

okay this list is long long — like, the whole MEI bus crew showed up to the group chat. all from the kernel file ./drivers/misc/mei/bus.c:

forty-six entries. forty-six!! the way this manpage said "here's the whole friend group" 💀💖

and that's the page!! sign-off time: this cutie is sourced from ./drivers/misc/mei, dated October 2026, and it's a kernel API manual moment. mwah 💋 periodt ✨🎀🦋
