✨ qcom_smem_alloc(9) ✨

okay so bestie, welcome to the Kernel API Manual 💖 this one's a little function from the Qualcomm SMEM world and honestly it's giving "tiny but essential" — it literally just carves out space for a smem item. no cap. let's get into it 🎀

🌸 NAME 🌸

qcom_smem_alloc — allocate space for a smem item 💅

---

⭐ SYNOPSIS ⭐

int qcom_smem_alloc (unsigned int host , unsigned int item , size_t size
);

---

🦋 ARGUMENTS 🦋

• host — the remote processor id, or -1. that's it, that's the whole vibe 👑
• item — the smem item handle 🎀
• size — how many bytes you want allocated, fr fr 🍓

---

💜 DESCRIPTION 💜

So what it does: it allocates space for a given smem item, sized size, given that the item is not yet allocated. that's the whole deal. queen behavior, no notes ✨

🔥 RETURN 🔥

• 0 on success 🎉
• a negative errno on failure 😭 (yeah, the sad path)
