fdt_next_property_offset(9)

✨ fdt_next_property_offset(9) ✨

okay so bestie, welcome to the Kernel API Manual entry for fdt_next_property_offset — literally the little function that walks you down a node's property list one step at a time. it's giving tour guide energy 🎀

---

💖 NAME 💖

fdt_next_property_offset — step through a node's properties 🦋

---

🌸 SYNOPSIS 🌸

int fdt_next_property_offset (const void *fdt , int offset );

---

🧚 ARGUMENTS 🧚

• fdt — pointer to the device tree blob, aka the whole vibe 💅
• offset — structure block offset of a property. you gotta hand it a property, not a node, not a random tag. a property.

---

🔥 DESCRIPTION 🔥

so fdt_next_property_offset finds the property immediately after the one sitting at the given structure block offset. and like — this is the important part, bestie — the one it hands back is a property of the same node as the given property. same node, next property, no cap ✨

---

⭐ RETURN ⭐

here's what you get back, and honestly the vibes vary:

• structure block offset of the next property (>=0), on success — slay 🎉
• -FDT_ERR_NOTFOUND, if the given property is the last in its node — yeah you hit the end of the line, it's over 😭
• -FDT_ERR_BADOFFSET, if nodeoffset did not point to an FDT_PROP tag — wrong item, bestie, wrong item 💀
• -FDT_ERR_BADMAGIC, -FDT_ERR_BADVERSION, -FDT_ERR_BADSTATE, -FDT_ERR_BADSTRUCTURE, -FDT_ERR_TRUNCATED — standard meanings, iykyk 🫶

💀 real talk: that -FDT_ERR_BADOFFSET is because someone passed a nodeoffset that didn't point at an FDT_PROP tag. check your tag before you come for this function, bestie 🙈
