like, look at her signature. chef's kiss. no notes. 💅

👑 ARGUMENTS 👑

okay here's the cast of characters, and yes every single one matters:

  • filp — the opened file, the whole reason we're here fr fr 🫶
  • buffer — where to write the data for the user to read. like, this is where the good stuff goes, be nice to it 💖
  • count — the size of the user's buffer. aka how much room we've got to work with, respect the limits bestie 🙈
  • ppos — file position offset. the "where are we even" of it all 📍

⭐ SEE ALSO ⭐

so there's a kernel file that lives at ./drivers/net/ethernet/intel/libie/fwlog.c (iconic path, no cap) and honestly? the whole friend group is here, let me introduce you:

like a whole squad. the read/write pairs? adorable. the init/deinit pairs? balanced. we love a stable ecosystem 💜

ngl bestie, this page is short and sweet — it's giving "small function, big responsibilities". read the room (literally, it's a read function) 🌈

okay and before you go — this whole thing came from ./drivers/net/ethernet/intel/l... (yes it's truncated in the source, don't come for me 🙈) and it's dated October 2026, so like... future-proofed AND iconic? we stan. 💀💖

mwah, go read some files, you're doing amazing sweetie 🎀✨🦋💅
