sgx_ioc_enclave_create(9)

NAME

hey bestie 💖 welcome to sgx_ioc_enclave_create(9) — that's the manual page, from the Kernel API Manual, and it's literally the handler for %SGX_IOC_ENCLAVE_CREATE. no cap.

---

SYNOPSIS

okay so here's the whole function signature, exact, no edits:

long sgx_ioc_enclave_create (struct sgx_encl *encl , void __user *arg );

---

ARGUMENTS

two args, both important, let's go 🫶

• encl — An enclave pointer. it's the enclave pointer, bestie — like, the actual pointer to the enclave.
• arg — The ioctl argument. this is the ioctl argument; that's the arg, periodt.

---

DESCRIPTION

so what does it do? it allocates the kernel data structures for the enclave and invokes ECREATE. that's the whole vibe ✨

---

RETURN

return values, bestie — memorize the vibe:

• 0 — Success. slay, it worked 🎉
• -EIO — ECREATE failed. oof, ECREATE failed 😭
• -errno — POSIX error. classic POSIX error territory.
