fdt_getprop_namelen(9)

okay so you're on the fdt_getprop_namelen(9) page from the Kernel API Manual, and it's literally about grabbing a property value based on a substring 💖 bestie, let's go.

---

💖 NAME 💖

fdt_getprop_namelen — get property value based on substring ✨

---

✨ SYNOPSIS ✨

the signature is right here, no cap:

const void * fdt_getprop_namelen (const void *fdt , int nodeoffset ,
const char *name , int namelen , int *lenp );

---

🎀 ARGUMENTS 🎀

• fdt — pointer to the device tree blob 🌳
• nodeoffset — offset of the node whose property to find 🔍
• name — name of the property to find 🏷️
• namelen — number of characters of name to consider ✂️
• lenp — pointer to an integer variable (will be overwritten) or NULL 🙈

---

🦋 DESCRIPTION 🦋

it's identical to fdt_getprop, but it only examines the first namelen characters of name for matching the property name. substring-match era, periodt 💅

---

🌸 RETURN 🌸

pointer to the property's value or NULL on error 🫶
