meson_spifc_transfer_one(9)

💅 meson_spifc_transfer_one(9) — from the Kernel API Manual, bestie

okay so picture this: you're deep in the kernel, right, and it's time to actually do the thing. This is the function that performs a single transfer. That's it, that's the whole vibe. One transfer. Not a whole conversation, just one little message. Slay.

✨ NAME ✨

meson_spifc_transfer_one — perform a single transfer

Like, literally just one. It's giving "one job, and it ate." 👑

---

🌸 SYNOPSIS 🌸

int meson_spifc_transfer_one (struct spi_controller *host , struct
spi_device *spi , struct spi_transfer *xfer );

Three args, one int coming back at you. That's the whole lineup. 🫶

---

🎀 ARGUMENTS 🎀

• host — the SPI host. Yes, the main character of the SPI world 💖
• spi — the SPI device. The one actually doing the thing, iykyk ✨
• xfer — the current SPI transfer. As in, this one. The transfer in question. 🌸

---

🦋 RETURN 🦋

• 0 on success 🎉
• a negative value on error 😭

no cap, that's the entire contract — zero means we ate, negative means something went sideways.
