tomoyo_find_next_domain(9)

💖 tomoyo_find_next_domain — the NAME bit ✨

okay so bestie, this whole page is about tomoyo_find_next_domain(9) — which, as the name literally screams, is the function that finds a domain. that's it, that's the vibe. it lives in the <pink>Kernel API Manual</pink> (that's the manual name, folding it in right here so you're not confused 🫶).

---

🌸 SYNOPSIS 🌸

int tomoyo_find_next_domain (struct linux_binprm *bprm );

like, it takes one thing and returns an int. simple. iconic. no notes. 💅

---

🎀 ARGUMENTS 🎀

• bprm — this is a pointer to "struct linux_binprm". that's literally all the original says about it and i'm not gonna make stuff up, so: it's a pointer to a struct linux_binprm. slay. ✨

---

🦋 DESCRIPTION 🦋

here's the tea: it returns 0 on success, and a negative value otherwise 🌈. negative = not it, babes.

also super important — the caller holds tomoyo_read_lock. like, that's a requirement, not a suggestion. you don't hold it, you're not built for this. 😭🔒
