spi_queued_transfer(9)

💅 spi_queued_transfer(9) — Kernel API Manual ✨

🌸 NAME 🌸

spi_queued_transfer — transfer function for queued transfers. That's literally it, bestie: it's the transfer function for queued transfers. 💅

---

🎀 SYNOPSIS 🎀

okay so here's the signature — keep it exactly as written, no edits, no vibes-based renaming:

int spi_queued_transfer (struct spi_device *spi , struct spi_message
*msg );

---

💅 ARGUMENTS 💅

bestie, there are two args and they're both important:

• spi — the SPI device that's requesting the transfer. 👑
• msg — the SPI message that's to be handled; it gets queued to the driver queue. 🫶

---

🎀 RETURN 🎀

It returns zero on success — iconic. Otherwise you get a negative error code, so check it, don't ignore it. 😭
