tomoyo_write_exception(9)

📦 version 7.3.1, in nixpkgs unstable

💅 tomoyo_write_exception(9) ✨

okay so bestie, we're deep in the Kernel API Manual, section 9, and the star of the show today is tomoyo_write_exception. she's a little function with a big job, and honestly? she ate. let's get into it 🫶

🌸 NAME 🌸

tomoyo_write_exception — writes the exception policy. that's it, that's the vibe. no cap. 💖

✨ SYNOPSIS ✨

int tomoyo_write_exception (struct tomoyo_io_buffer *head );

literally the whole signature, character for character, don't @ me 💅

🎀 ARGUMENTS 🎀

  • head — a pointer to "struct tomoyo_io_buffer". yes the quotes are in the original, she's quirky like that 🦋

👑 DESCRIPTION 👑

okay so the tea: it returns 0 on success, and a negative value otherwise. that's the entire contract, bestie. zero means slay, negative means something went sideways 😭

also, and this is important — the caller holds tomoyo_read_lock. like, the caller. not this function. so if you're calling it, you better already be holding that lock, fr fr. 🔥

🌈 SEE ALSO 🌈

this is the part where the manpage goes absolutely feral and lists everyone in the group chat. like, there are so many. buckle up 🎢

like okayyy mutuals 💅 also the kernel file lives at ./security/tomoyo/common.c, just so you know where the source is at. iykyk 🧚

ngl if you got this far you're genuinely built different. sixty-five cross-references and you didn't scroll once. main character energy fr 😭👑

🍓 a lil sign-off 🍓
