__mei_cl_recv(9)

📦 version 7.3.1, in nixpkgs unstable

💜 __mei_cl_recv — NAME

okay so bestie, this is __mei_cl_recv — the internal client receive (read) function. lowercase "internal" is doing a lot of work there, iykyk: this is the plumbing behind the friendly wrapper, the read side of an MEI client conversation. 🎀

This page lives in the Kernel API Manual section (that's section 9, for the kernel-curious). 🌸

✨ SYNOPSIS ✨

ssize_t __mei_cl_recv (struct mei_cl *cl , u8 *buf , size_t length , u8 *vtag , unsigned int mode , unsigned long timeout );

six arguments, one ssize_t coming back at you. it's giving "short and loaded". 💅

🫶 ARGUMENTS 🫶

  • cl — the host client. this is the client, the main character of this whole operation. 👑
  • buf — the buffer to receive. where the good stuff lands. 🍓
  • length — the buffer length. gotta tell it how much room there is, no cap. 📏
  • vtag — the virtual tag. yes it's a pointer, yes it matters. 🏷️
  • mode — the io mode. the vibe in which the io happens. 🌈
  • timeout — the recv timeout, and heads up: 0 means infinite timeout. zero = forever, which is honestly so on brand. ⏳💀

⭐ RETURN ⭐

it returns the read size in bytes — and if something went wrong it hands you a value < 0 on error. so like, check your return values, bestie, that's the whole point. 😭

fr fr: a negative return = error. don't just vibe past it.

okay that's the page!! 💖 this one's straight out of ./drivers/misc/mei, dated October 2026 — mwah, go forth and receive, bestie 🫶✨
