rethook_try_get(9)

💅 rethook_try_get(9) 💅

okay so bestie, welcome to the Kernel API Manual — yes it's giving official-docs energy but we're gonna make it make sense 🫶

---

✨ NAME ✨

rethook_try_get — grab yourself an unused rethook node, no cap 🌸

---

✨ SYNOPSIS ✨

struct rethook_node * rethook_try_get (struct rethook *rh );

like, that's the whole vibe. it returns a struct rethook_node * and it takes exactly one arg. periodt 💅

---

✨ ARGUMENTS ✨

• rh — the struct rethook that pools the nodes. think of it as the group chat where all the nodes hang out, and you're about to slide into it and steal one 🎀

---

✨ DESCRIPTION ✨

so basically: get an unused rethook node from rh. it's giving "borrow a charger from your bestie" energy 🔥

and here's the important part — if the node pool is empty, this will return NULL. not a vibe, but that's the deal 😭 so like, check for NULL, okay? don't just assume you got one.

⚠️ fr fr warning: caller must disable preemption. like actually. not "I'll do it later" — disable it before you call this. no cap 💀
