ne_enclave_ioctl(9)

💖 NAME 💖

Okay so welcome to ne_enclave_ioctl(9), bestie — this is from the Kernel API Manual, and it's the ioctl function provided by the enclave file. Literally that's the whole vibe ✨.

✨ SYNOPSIS ✨

The signature, no cap:

long ne_enclave_ioctl (struct file *file , unsigned int cmd , unsigned long arg );

🫶 ARGUMENTS 🫶

• file — the file associated with this ioctl function. Bestie, that's the file in question 🫶
• cmd — the command that is set for the ioctl call.
• arg — the argument that is provided for the ioctl call.

🌈 CONTEXT 🌈

Process context. That's it. That's the context check — process context, periodt 🦋.

🎀 RETURN 🎀

• 0 on success — slay ✅
• Negative return value on failure — okay so it's giving “not today,” but that's the documented return 💀
