pdcs_diagnostic_read(9)

📦 version 7.3.1, in nixpkgs unstable

💅 pdcs_diagnostic_read(9) — like, the whole page ✨

okay so bestie, this is a page from the Kernel API Manual, section 9, and it's about one very specific little function. Let's get into it 🎀

🌸 NAME 🌸

pdcs_diagnostic_read — literally just spits out the Stable Storage Diagnostic register. That's the whole vibe, no cap.

✨ SYNOPSIS ✨

ssize_t pdcs_diagnostic_read (struct kobject *kobj , struct
kobj_attribute *attr , char *buf );

yes the line break in the middle is real, we keep it exactly as it is, we don't fix it, periodt 💅

🦋 ARGUMENTS 🦋

  • kobj — the kobject that's used to share data with userspace. it's the little handshake between kernel and user world, iykyk 🫶
  • attr — the kobject attributes. the ~vibes~ of the kobject, basically ✨
  • buf — the output buffer you write to. this is where the reading goes, bestie 💖

🌈 DESCRIPTION 🌈

I have NFC how to interpret the content of that register ;-).

that's it. that's the description. the original author said what they said and honestly? iconic. main character energy fr fr 👑 not me being obsessed with a kernel dev admitting they don't know what the register means 💀

🍓 SEE ALSO 🍓
