ne_sanity_c...r_mem_region(9)

🎀 NAME 🎀

okay so bestie, this is the ne_sanity_check_user_mem_region(9) page from the Kernel API Manual ✨ and it does exactly what it says on the tin: it sanity-checks the user space memory region that showed up during the set user memory region ioctl call. no cap, that's the whole vibe 💅

---

🌸 SYNOPSIS 🌸

int ne_sanity_check_user_mem_region (struct ne_enclave *ne_enclave ,
struct ne_user_memory_region mem_region );

---

🦋 ARGUMENTS 🦋

• ne_enclave — private data associated with the current enclave. it's giving "main character struct" energy 👑
• mem_region — the user space memory region that needs to be sanity checked. yes, this is the one getting the vibe check 🔍

---

💜 CONTEXT 💜

Process context. This function is called with the ne_enclave mutex held. like, the lock is already in the group chat, bestie — don't double-text it 🫶

---

✨ RETURN ✨

• 0 on success — slay, everything checks out 💖
• A negative return value on failure — not iconic, but important 😭
