✨ ofdt_write(9) ✨

okay bestie, welcome to the Kernel API Manual, section 9 — this is the page for ofdt_write, and ngl it's lowkey a little cryptic but we're gonna get through it together 💖

---

🌸 NAME 🌸

ofdt_write — perform operations on the Open Firmware device tree

Like, you're literally reaching into the Open Firmware device tree and doing stuff to it. main character energy fr fr 👑

---

🦋 SYNOPSIS 🦋

ssize_t ofdt_write (struct file *file , const char __user *buf , size_t
count , loff_t *off );

That's the whole signature, keep it exactly like that, no notes 💅

---

🎀 ARGUMENTS 🎀

• file — not used 🙈 like she's literally just there, sitting in the parameter list, contributing nothing. we stan a decorative queen.
• buf — the command and its arguments. this is the important one, she's carrying the whole vibe.
• count — size of the command buffer. gotta tell us how much of buf is actually real.
• off — not used. another icon doing absolutely nothing, and honestly? respect 🫶

---

⭐ DESCRIPTION ⭐

so here's the tea: the operations supported at this time are addition and removal of whole nodes, along with their properties. that's it, that's the whole menu 🍓

⚠️ and listen — operations on individual properties are not implemented (yet). like, don't come for her, she's working on it. but right now if you try to be cute with a single property, that's simply not on the table, bestie 😭
