genwqe_finish_queue(9)

💖 genwqe_finish_queue — Kernel API Manual, bestie edition 💖

okay so real talk, we're in the genwqe_finish_queue(9) man page today and honestly? it's a little cleanup anthem and i respect it. grab a strawberry 🍓 and let's get into it.

---

✨ NAME ✨

genwqe_finish_queue — literally just remove any genwqe devices and user-interfaces. like packing up the whole party at the end of the night 🎀

---

🌸 SYNOPSIS 🌸

int genwqe_finish_queue (struct genwqe_dev *cd );

that's it. that's the whole vibe check. one function, one pointer, one int coming back at you 💅

---

🦋 ARGUMENTS 🦋

• cd — pointer to the genwqe device descriptor. iconic little handle, she knows things about the device 👑

---

🔥 DESCRIPTION 🔥

so here's the tea. this function relies on a pre-condition: there are no users of the card device anymore — like, zero, none, nobody. think open file-descriptors still lurking around? yeah, that's a no-go. the card needs to be fully abandoned by everybody before you call this, fr fr 🙈

and the other thing — highkey important — this function must be robust enough to be called twice. yes bestie, twice. it should survive that. no cap. 🫶
