fdt_get_phandle(9)

💖 fdt_get_phandle(9) 💖

okay bestie, welcome to the Kernel API Manual page for fdt_get_phandle — it's lowkey a tiny little function with main character energy, and we are gonna get you comfy with it. ✨

---

🎀 NAME 🎀

fdt_get_phandle — retrieve the phandle of a given node 💅

---

🌸 SYNOPSIS 🌸

uint32_t fdt_get_phandle (const void *fdt , int nodeoffset );

---

🎀 ARGUMENTS 🎀

• fdt — pointer to the device tree blob 🫶
• nodeoffset — structure block offset of the node 💅

---

🦋 DESCRIPTION 🦋

okay so fdt_get_phandle retrieves the phandle of the device tree node at structure block offset nodeoffset. That's literally the whole mission bestie — no extra plot twists, no side quests, just the phandle retrieval situation. ✨

---

🔥 RETURN 🔥

here's the vibe check on what comes back:

• On success, you get the phandle of the node at nodeoffset — and success here means != 0 and != -1. 💖
• You get 0 if the node has no phandle, or another error occurs. 😭
