btree_destroy(9)

💅 btree_destroy(9) — the Kernel API Manual glow-up

okay so bestie, welcome to btree_destroy(9) — yes, section 9, the kernel-funcs girlypop section, we love her 💖

---

✨ NAME ✨

btree_destroy — destroy mempool 🧚

like, she destroys the mempool. that's the whole vibe. no cap.

---

🌸 SYNOPSIS 🌸

void btree_destroy (struct btree_head *head );

that's it. one function, one argument, zero drama (well, almost — see DESCRIPTION, bestie, there's a whole caveat) 🫶

---

🎀 ARGUMENTS 🎀

• head — the btree head to destroy 💀 literally the thing you're sending to the void. it's the struct btree_head * from the synopsis, and yes, you gotta hand her over.

---

💜 DESCRIPTION 💜

so what does she actually do? this function destroys the internal memory pool ✨ periodt. the pool is gone. she ate. 🔥

but bestie, listen to me, come closer, this is the important part 🙈:

use this only when using btree_init — and NOT with btree_init_mempool 🚨

like, the vibe check here is real. btree_destroy and btree_init are a matched set, they're endgame, they're the main characters together 💅. btree_init_mempool is a different setup and she does not get this destroy call. pairing them up is not it, ngl. so know which init you used before you call this, fr fr 🦋
