binder_proc_dec_tmpref(9)

💅 binder_proc_dec_tmpref(9) — like, the kernel API manual, bestie 🎀

okay so welcome to the binder_proc_dec_tmpref page from the Kernel API Manual — yes that's the manual name, we're being fancy today ✨ grab a strawberry 🍓 and let's get into it.

---

✨ NAME ✨

binder_proc_dec_tmpref — literally just decrements proc->tmp_ref. that's the whole job. no cap. 💅

---

🦋 SYNOPSIS 🦋

void binder_proc_dec_tmpref (struct binder_proc *proc );

---

🌸 ARGUMENTS 🌸

• proc — the proc you wanna decrement, bestie. that's the one. 🫶

---

👑 DESCRIPTION 👑

so here's the vibe check 👀 — a binder_proc needs to be kept alive while it's being used to create or handle a transaction. like, you can't just let it dip mid-transaction, that would be giving chaos energy 😭

proc->tmp_ref gets incremented when:

• a new transaction is being created, or
• the binder_proc is currently in-use by threads that are being released

and then when you're done with the binder_proc, you call this function to decrement the counter and free the proc if appropriate 🔥

"if appropriate" means: proc has been released, all threads have been released, and it's not currently in-use to process a transaction. all three, bestie. no shortcuts. ⭐
