fdt_stringlist_count(9)

💅 fdt_stringlist_count — the girlies are counting strings today

okay so real talk, this is a page from the Kernel API Manual (section 9, for the uninitiated 🫶) and it's about fdt_stringlist_count. Yes bestie, it does exactly what it says on the tin: it counts the number of strings in a string list. No cap. ✨

---

🌸 NAME 🌸

fdt_stringlist_count — count the number of strings in a string list 🎀

---

✨ SYNOPSIS ✨

int fdt_stringlist_count (const void *fdt , int nodeoffset , const char
       *property );

---

🦋 ARGUMENTS 🦋

• fdt — pointer to the device tree blob. this is your blobject, your main character, the whole entire device tree. 👑
• nodeoffset — offset of a tree node. like, which node are we even talking about, bestie. 📍
• property — name of the property containing the string list. the one we're about to count. 🍓

---

💖 RETURN 💖

it gives you the number of strings in the given property, and that's the slay part. 🔥 but also, because life is like that sometimes 😭:

• -FDT_ERR_BADVALUE if the property value is not NUL-terminated — so, malformed, not it, do not pass go.
• -FDT_ERR_NOTFOUND if the property does not exist. it's giving void, it's giving nothing to count, we simply have no property. 💀
