_xbc_exit(9)

👑 _xbc_exit — the Kernel API Manual glow-up ✨

okay so bestie, welcome to the _xbc_exit(9) page from the Kernel API Manual — yes we're in kernel-land today, and no, it's not scary, i promise 🫶

---

🌸 NAME 🌸

_xbc_exit — the little cleanup queen that wipes all your parsed bootconfig 🧹💅

---

✨ SYNOPSIS ✨

void _xbc_exit (bool early );

that's it. that's the whole signature. void in, void out, no return value, no drama (for once) 😌

---

🎀 ARGUMENTS 🎀

• early — set this to true if you're calling it before the body system is initialized. literally just a "hey, are we super early or not" boolean, that's the whole vibe 🦋

---

💖 DESCRIPTION 💖

okay so what does this actually do? _xbc_exit clears all the data structures of your parsed bootconfig out of memory 🔥 like, full reset, memory's clean, nothing left behind. it's giving responsible adult energy, honestly.

and the reason you'd ever want that? if you need to reuse xbc_init with a new boot config, you can call this first. so like — out with the old, in with the new, slay ✨ it's the "close one tab before opening another" of kernel functions, iykyk 💀

ngl, it's a lifecycle thing — this is the exit half of the pair. xbc_init gets you in, _xbc_exit gets you out, periodt.
