✨ NAME ✨

drm_eld_size — Get ELD size in bytes</p> 💅 that's it, that's the job

---

🌸 SYNOPSIS 🌸

int drm_eld_size (const u8 *eld );

---

🎀 ARGUMENTS 🎀

• eld — pointer to a complete eld memory structure ✨ like, a complete one, okay? don't come at it with a half-built struct, she needs the whole vibe

---

🦋 DESCRIPTION 🦋

So the number you get back? It does not include the vendor block, okay 😤 that part is vendor specific and it's made up of whatever bytes are left over in the ELD memory buffer after drm_eld_size bytes of header and baseline block. Like the vendor block is the lil bonus content at the end and we're not counting it 📭

And here's the tea: the returned value is guaranteed to be a multiple of 4 ✨ so don't be out here expecting 7 or 13, it's giving divisible-by-four main character energy 👑
