class_destroy(9)

✨ class_destroy(9) ✨

okay bestie, so this one is a little kernel API manual page — class_destroy(9) — and honestly? it's giving "short but important" energy. no cap, it's a tiny one, but you need to know it. let's get into it 💅

---

🌸 NAME 🌸

class_destroy — destroys a struct class structure. literally what it says on the tin, bestie. it's the cleanup bestie to class_create. 🫶

---

🦋 SYNOPSIS 🦋

void class_destroy (const struct class *cls );

that's it. that's the whole signature. void return, one argument, no drama. ✨

---

🎀 ARGUMENTS 🎀

• cls — pointer to the struct class that is to be destroyed. like, the actual one you want gone. not a copy, not a vibe, the pointer itself. 💖

---

👑 DESCRIPTION 👑

okay so the one thing to remember here, and i mean the thing:

Note, the pointer to be destroyed must have been created with a call to class_create.

fr fr. if you didn't make it with class_create, do not hand it to class_destroy. that's the whole rule. it's not a suggestion, it's the rule. 😭
