pdcs_osdep2_read(9)

📦 version 7.3.1, in nixpkgs unstable

💅 pdcs_osdep2_read — like, from the Kernel API Manual, bestie ✨

Okay so picture this: it's a (9) section page, it lives in the Kernel API Manual, and it's all about pulling "Stable Storage OS-Dependent data area 2" back out into the world. Iconic behavior honestly. 🎀

✨ NAME ✨

pdcs_osdep2_read — the one that does Stable Storage OS-Dependent data area 2 output. That's it, that's the whole vibe. 🦋

🌸 SYNOPSIS 🌸

ssize_t pdcs_osdep2_read (struct kobject *kobj , struct kobj_attribute
*attr , char *buf );

yep that's the whole signature, no cap, ssize_t and everything 💜

🫶 ARGUMENTS 🫶

  • kobj — the struct kobject that's literally the little social butterfly sharing data with userspace. it's giving main character energy tbh.
  • attr — the struct kobject attributes. the ~vibes~ attached to the kobject, if you will. ✨
  • buf — the output buffer you write to. this is the destination bestie, the place the data goes. 💌

🧚 DESCRIPTION 🧚

So when it's actually available, this thing can hold pdcs_size - 224 bytes of OS-Dependent data. that's the math, that's the tea, pdcs_size minus 224, do not @ me. 🔥

lowkey important: it holds that much when available — the key phrase is when available, so don't come for me if it's not there 🙈

👑 SEE ALSO 👑
