rethook_free(9)

🎀 rethook_free(9) 🎀

✨ NAME ✨

okay so bestie, this page is from the Kernel API Manual, and it's all about rethook_free — which frees struct rethook, literally what it says on the tin. 💅

💖 SYNOPSIS 💖

void rethook_free (struct rethook *rh );

🦋 ARGUMENTS 🦋

• rh — the struct rethook to be freed. ✨

🔥 DESCRIPTION 🔥

okay so here's the tea: this function frees the rethook. Before you call it, you — the user — must make sure rh::data is cleaned if needed. (Or, the handler can access it after calling this function.) no cap, that parenthetical is important. 🫶

This function will set the rh to be freed after all rethook_node are freed — and yes, not soon. So don't expect it to happen instantly. 🙈

And the caller must not touch rh after calling this. Like, hands off, bestie. periodt. 💀
