spi_get_next_queued_message(9)

💅 spi_get_next_queued_message(9) — like, the Kernel API Manual edition 🎀

okay bestie, gather round, because this one is short and sweet and honestly kind of iconic in its simplicity ✨

---

✨ NAME ✨

spi_get_next_queued_message — the little function a driver calls to check if there's anything queued up and waiting 💌

---

🌸 SYNOPSIS 🌸

struct spi_message * spi_get_next_queued_message (struct spi_controller
*ctlr );

---

🦋 ARGUMENTS 🦋

• ctlr — the controller you want to peek at for queued messages 👀 that's it, that's the whole argument, no cap

---

💖 DESCRIPTION 💖

If there are more messages sitting in the queue, the next message gets returned from this call 🫶. Like, you ask "is there another one?" and if yes, boom, here's your message. The way that it just hands it to you 😭 so efficient.

---

⭐ RETURN ⭐

The next message in the queue — or NULL if the queue is empty 💀 (empty queue = nothing for you, bestie, sorry, go touch some registers 🌈).
