tomoyo_open_control(9)

💖 NAME 💖

okay so bestie, welcome to tomoyo_open_control(9) — yep, that's the Kernel API Manual page, and it's literally the open() for the /sys/kernel/security/tomoyo/ interface. that's the whole vibe. 🦋

✨ SYNOPSIS ✨

int tomoyo_open_control (const u8 type , struct file *file );

🎀 ARGUMENTS 🎀

• type — type of interface. that's the assignment, no cap.
• file — pointer to "struct file". yes bestie, the file struct itself. 🫶

🦋 DESCRIPTION 🦋

returns 0 on success, and a negative value otherwise. that's it. that's the plot. ✨

lowkey important: 0 means success, and a negative value means not success. don't forget the negative part, bestie 💅
