init_bios_attributes(9)

💅 init_bios_attributes — the kernel API manual, bestie edition 🎀

ok so this is a page from the Kernel API Manual (yes, the kernel has lore and it's giving main character energy) and today's episode is all about init_bios_attributes. buckle up 🦋

---

✨ NAME ✨

init_bios_attributes — literally initializes all the attributes for a type. like, all of them. no crumbs left 🫶

---

✨ SYNOPSIS ✨

int init_bios_attributes (int attr_type , const char *guid );

---

✨ ARGUMENTS ✨

• attr_type — the attribute type you wanna initialize. that's the one, bestie 🎯
• guid — the WMI GUID that's associated with this type you're initializing. yes it's long, yes it's ugly, copy-paste it and move on 😭

---

✨ DESCRIPTION ✨

so what it does is initialize all 4 types of attributes — that's enumeration, integer, string and password object 🔥 (four whole vibes, iconic lineup honestly).

then it populates each attribute type's respective properties under the sysfs files. so every type gets its own lil moment in sysfs 💖
