fdt_get_name(9)

🎀 NAME 🎀

okay so bestie, this is fdt_get_name(9) from the Kernel API Manual, and it's here to retrieve the name of a given node. That's the whole vibe 💖.

✨ SYNOPSIS ✨

const char * fdt_get_name (const void *fdt , int nodeoffset , int *lenp
       );

🦋 ARGUMENTS 🦋

• fdt — pointer to the device tree blob. literally the tree.
• nodeoffset — structure block offset of the starting node.
• lenp — pointer to an integer variable (will be overwritten) or NULL.

💅 DESCRIPTION 💅

fdt_get_name retrieves the name (including unit address) of the device tree node at structure block offset nodeoffset. If lenp is non-NULL, the length of this name is also returned, in the integer pointed to by lenp. periodt ✨

🔥 RETURN 🔥

On success, you get a pointer to the node's name. If lenp is non-NULL, *lenp contains the length of that name (>=0). 🫶

On error, you get NULL. If lenp is non-NULL, *lenp contains an error code (<0):

• -FDT_ERR_BADOFFSET — nodeoffset did not point to FDT_BEGIN_NODE tag
• -FDT_ERR_BADMAGIC, -FDT_ERR_BADVERSION, -FDT_ERR_BADSTATE — standard meanings

ahh, and the little footer moment: this page is from ./scripts/dtc/libfdt, dated October 2026, and yes bestie, it's still fdt_get_name(9) 💋✨
