nvmem_dev_size(9)

💖 nvmem_dev_size (9) — a Kernel API Manual moment 💖

okay so bestie, welcome to the Kernel API Manual entry for nvmem_dev_size and honestly? she's a short one, but she's iconic. no cap. 🎀

---

✨ NAME ✨

nvmem_dev_size — get the size of a given nvmem device. that's it. that's the whole vibe. lowkey the most straightforward function in the whole nvmem cinematic universe 🦋

---

🌸 SYNOPSIS 🌸

size_t nvmem_dev_size (struct nvmem_device *nvmem );

like, you hand her a device and she hands you back a size_t. transactional queen 💅

---

💜 ARGUMENTS 💜

• nvmem — nvmem device. literally just the device, bestie. that's the whole argument. one (1) singular device. go off, minimalism 👑

---

⭐ RETURN ⭐

size of the nvmem device. she returns it. that's the answer. size_t-shaped, device-sized, done. 🔥

the whole friend group shows up for this one, iykyk. and also the kernel file ./drivers/nvmem/core.c gets a shoutout, because that's where the magic lives 💫

bestie note: everything above is documented, none of it is me guessing. if you need the lore, ./drivers/nvmem/core.c is the source of truth. 🫶
