pdcs_osdep2_write(9)

📦 version 7.3.1, in nixpkgs unstable

💾 pdcs_osdep2_write — it's giving "stable storage, OS-dependent data area 2, but make it input" ✨

okay bestie, welcome to pdcs_osdep2_write(9) from the section 9 kernel API manual — yes, that's the manual name right there, section 9, kernel API vibes only 💅

🌸 SYNOPSIS 🌸

ssize_t pdcs_osdep2_write (struct kobject *kobj , struct kobj_attribute
*attr , const char *buf , size_t count );

look at her. iconic signature. no notes. 🫶

🎀 ARGUMENTS 🎀

  • kobj — the kobject she uses to share data with userspace. like, that's the whole communication channel, bestie, that's the group chat 📱
  • attr — the kobject attributes. the metadata bestie. the vibe descriptor 💫
  • buf — the input buffer you're reading from. this is what you're feeding her 🍓
  • count — how many bytes are gonna be read. the headcount. the guest list 🔢

🦋 DESCRIPTION 🦋

so here's the tea ☕ — this function can store pdcs_size - 224 bytes of OS-Dependent data. no cap, that's the capacity.

she uses a byte-by-byte write approach, which is exactly what it sounds like: one lil byte at a time, no bundling, no shortcuts 💀

and the important part: it's up to userspace to deal with it when constructing its input buffer. so like… that's on you, bestie. you build the buffer, you handle the layout. she's just writing. main character energy but the character is you 🙈

ngl, don't come for her about the byte-by-byte thing — that's just how she rolls. you handle your buffer construction, she'll handle the bytes. teamwork ✨

and that's the whole page, bestie 💜 this lil gem lives in ./drivers/parisc and the version stamp says October 2026 — so like, future-coded AND stable-storage-coded. iykyk 🧚‍♀️💖
