fdt_create(9)

💖 NAME 💖

fdt_create — bestie, this is the “begin creation of a new fdt” moment. Like the opening scene of your fdt’s main character era. ✨ This is the fdt_create(9) page, and we’re keeping it cute.

---

🌸 SYNOPSIS 🌸

int fdt_create (void *buf , int bufsize );

---

🎀 ARGUMENTS 🎀

• buf — pointer to memory allocated where fdt will be created. 💖 You bring the memory, this function brings the fdt glow-up.
• bufsize — size of the memory space at fdt. 💅 That’s how much room your new fdt gets.

---

🦋 DESCRIPTION 🦋

Okay so lowkey the whole vibe is simple: fdt_create is equivalent to fdt_create_with_flags with flags=0. Periodt. 💜

No hidden lore — just the zero-flags equivalent, exactly as stated. ✨

---

⭐ RETURN ⭐

• 0 — on success, slay! ✨
• -FDT_ERR_NOSPACE — bufsize is insufficient for a minimal fdt. Oop, there’s not enough room for even a minimal baby fdt 😭.

bestie, that’s the exact error case: bufsize is insufficient for a minimal fdt. No cap. 😭
