sgx_encl_remove_pages(9)

💅 sgx_encl_remove_pages — a Kernel API Manual moment (section 9, bestie)

okay so this is the sgx_encl_remove_pages(9) page, and yes we're reading kernel API docs for fun now, that's just who we are 💖

✨ NAME ✨

sgx_encl_remove_pages — literally just Remove trimmed pages from SGX enclave. that's the whole vibe. trimmed pages? gone. removed. slay.

🌸 SYNOPSIS 🌸

long sgx_encl_remove_pages (struct sgx_encl *encl , struct
sgx_enclave_remove_pages *params );

like, copy that exactly bestie, every character matters, no cap 🫶

🎀 ARGUMENTS 🎀

• encl — the enclave that these pages belong to. it's giving "whose pages are these" energy. the pages lowkey live here 💅
• params — checked parameters from user, telling us which pages need to be removed. the word "checked" is doing so much work here and we love her for it ✨

🔥 RETURN 🔥

• 0 — Success. we ate. periodt 👑
• -errno — Otherwise. so like, anything else, and you're getting an errno back. not the win we wanted but honestly valid 😭
