platform_profile_store(9)

💅 platform_profile_store(9) 💅

okay so bestie, welcome to platform_profile_store(9) — literally the kernel API manual page, and yes we're reading it together, it's giving study date energy 🎀

This one is platform_profile_store — the function that sets the profile for the legacy sysfs interface. That's the whole vibe. Legacy. Sysfs. Profile-setting. Slay. 🦋

---

✨ SYNOPSIS ✨

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

four arguments, one ssize_t coming back at you, no cap 💅

---

🌸 ARGUMENTS 🌸

• kobj — the kobject. that's it, that's the whole description. it's the kobject, bestie 🫶
• attr — the attribute. iconic, no notes ✨
• buf — the buffer to read from. this is where the good stuff lives 🎀
• count — the number of bytes to read. respect the count, always 😌

---

💖 RETURN 💖

the number of bytes read 🔥 that's the whole return story, periodt.

ngl this manpage is short and sweet and we respect that — not every page needs to be a whole saga 💀
