binder_alloc_init(9) 🎀

hey bestie, welcome to the Kernel API Manual page for binder_alloc_init(9) — yes, it’s giving tiny-but-iconic kernel init energy ✨

---

🌸 NAME 🌸

binder_alloc_init — the one called by binder_open() for per-proc initialization, no cap 💅

---

✨ SYNOPSIS ✨

void binder_alloc_init (struct binder_alloc *alloc );

that’s the whole signature, bestie — void return, one pointer arg, slay 🫶

---

💖 ARGUMENTS 💖

• alloc — the binder_alloc for this proc. that’s it, that’s the whole argument, and it’s lowkey main character energy for this call 🦋

---

🦋 DESCRIPTION 🦋

Called from binder_open to initialize binder_alloc fields for a new binder proc. so when a fresh binder proc shows up, this is the lil init moment where its binder_alloc fields get set up — literally the per-proc prep step, periodt ✨

bestie, this one is short and sweet — don’t blink, you’ll miss the whole function 💀
