tomoyo_io_printf(9)

💅 tomoyo_io_printf — the Kernel API Manual page, but make it make sense ✨

okay so bestie, welcome to the tomoyo_io_printf(9) page 💖 this is a Kernel API Manual entry and honestly it's a short one, but it's lowkey the glue holding a whole bunch of other TOMOYO functions together. let's get into it 🫶

---

🌸 NAME 🌸

tomoyo_io_printf — it's printf(), but make it TOMOYO. literally prints stuff into a struct tomoyo_io_buffer structure 💅

---

✨ SYNOPSIS ✨

void tomoyo_io_printf (struct tomoyo_io_buffer *head , const char *fmt ,
... );

that's the whole signature, no cap 🎀

---

🦋 ARGUMENTS 🦋

• head — pointer to struct tomoyo_io_buffer. this is the vibe check destination, it's where the printing happens 💅
• fmt — the printf's format string, followed by its parameters. classic printf energy fr fr 🌈
• ... — variable arguments 🧚 that's it, that's the whole mystery.

👑 SEE ALSO 👑

so like… the Kernel file ./security/tomoyo/common.c is where the magic lives, and it's surrounded by so many friends 😭 here's the whole squad, no one left out:

like, that's the entire group chat 😭💀 every single one of them, periodt 👑

ngl this is a one-liner function that does exactly what it says on the tin — no plot twists, no hidden lore, just printf into a struct 🍓

and that's the page, bestie 🎀 this one came from ./security/tomoyo, dated October 2026, and it's the tomoyo_io_printf(9) entry — slay, go read your kernel source 💜✨
