STRUCT IIO_SCAN_TYPE(9)

👑 struct iio_scan_type(9) 👑

okay so bestie, welcome to the Kernel API Manual ✨ this page is literally all about struct iio_scan_type, and it's giving “specification for channel data format in buffer” energy 💅

🌸 NAME 🌸

struct iio_scan_type — specification for channel data format in buffer 🫶

✨ SYNOPSIS ✨

       struct iio_scan_type {
           union {
             char sign;
             char format;
           };
           u8 realbits;
           u8 storagebits;
           u8 shift;
           u8 repeat;
           enum iio_endian endianness;
        };

🎀 Members 🎀

• {unnamed_union} — anonymous, bestie. No name, just anonymous union vibes 🙈
• sign — deprecated, use format instead. it's the old one, okay? 😭
• format — data format, can have any of the IIO_SCAN_FORMAT_* values. iconic 🌈
• realbits — number of valid bits of data. literally the real ones 💖
• storagebits — Realbits + padding. so, real bits plus the padding situation ✨
• shift — shift right by this before masking out realbits. yes ma’am 🫡
• repeat — number of times real/storage bits repeats. When the repeat element is more than 1, then the type element in sysfs will show a repeat value. Otherwise, the number of repetitions is omitted. periodt 💅
• endianness — little or big endian. endian girlies rise 🦋

cute lil sign-off: this page comes from source ./include/linux/iio, dated October 2026, and it's literally struct iio_scan_type(9) — mwah 💋🎀
