iio_dma_buff...es_per_datum(9)

🌸 iio_dma_buffer_set_bytes_per_datum — the manual, but make it make sense 💅

okay so bestie, this is a page from the Kernel API Manual (yes, the kernel, we're fancy now) and it's about iio_dma_buffer_set_bytes_per_datum ✨

---

✨ NAME ✨

iio_dma_buffer_set_bytes_per_datum — the DMA buffer's set_bytes_per_datum callback, no cap 🫶

---

🦋 SYNOPSIS 🦋

int iio_dma_buffer_set_bytes_per_datum (struct iio_buffer *buffer ,
                                        size_t bpd );

---

🎀 ARGUMENTS 🎀

• buffer — the buffer you're setting the bytes-per-datum for. literally the main character here 👑
• bpd — the new bytes-per-datum value. the glow-up number fr fr 🔥

---

💖 DESCRIPTION 💖

okay so here's the vibe: you should use this as the set_bytes_per_datum callback for the iio_buffer_access_ops struct when you're dealing with DMA buffers. that's it, that's the whole assignment 💅 periodt.

ngl there's not a ton here, but that's on purpose — it's a callback, not a whole saga 🙈
