STRUCT IIO_DMABUF(9)

💖 struct iio_dmabuf(9) 💖

okay so this page comes from the Kernel API Manual, and it's all about one little struct that describes a DMABUF object. Bestie, it's short but it matters 💅

✨ NAME ✨

struct iio_dmabuf - Descriptor for a single IIO DMABUF object. Like, literally the descriptor for one IIO DMABUF object, no cap 🫶

🦋 SYNOPSIS 🦋

       struct iio_dmabuf {
           __u32 fd;
           __u32 flags;
           __u64 bytes_used;
        };

🎀 Members 🎀

• fd — file descriptor of the DMABUF object 🔥
• flags — one or more IIO_BUFFER_DMABUF_* flags 🎀
• bytes_used — number of bytes used in this DMABUF for the data transfer. It should generally be set to the DMABUF's size. Yes, that's the move 💅

👀 SEE ALSO 👀

• Kernel file ./include/uapi/linux/iio/buffer.h — go peek at it, bestie, it's the reference 🌸

xoxo 💋 — from ./include/uapi/linux/iio (source/version), dated October 2026, and yes, the page is struct iio_dmabuf(9) 🫶✨
