fdt_end_node(9)

Hiiii bestie! 🌸 Welcome to the <pink>Kernel API Manual</pink> entry for fdt_end_node — the <purple>fdt_end_node(9)</purple> page, to be exact. And ngl? This one's short but it's crucial if you're out here building device tree blobs sequentially. Let's get into it. 💅

✨ NAME ✨

fdt_end_node — complete the current node 🎀

🌸 SYNOPSIS 🌸

int fdt_end_node (void *fdt );

🦋 ARGUMENTS 🦋

• fdt — pointer to the device tree blob 🌳. That's literally it. Just the blob you're working on.

🍓 DESCRIPTION 🍓

Okay so picture this: you're doing a sequential write of a device tree blob, right? fdt_end_node is the function that completes the current node. ✨

Here's the vibe check: you must call this function to close each node you started with fdt_begin_node. No cap. Every single node needs its ending moment. 🫶

And after you call this? Bestie, listen. No more properties or subnodes can be added to the node. It's giving "the end, periodt." 💀 So make sure you've added everything you wanted before you hit this function.

🔥 RETURN 🔥

• 0 — on success 🎉 slay!
• -FDT_ERR_BADSTATE — if you're not currently within a node 😭. Basically the function is like "bestie, there's no node to end?" — check your state, iykyk.
