STRUCT IIO_CHAN_SPEC_EXT_INFO(9)

💅 struct iio_chan_spec_ext_info(9) 💅

okay so bestie, this page is from the Kernel API Manual, and it's literally the extended channel info attribute. no cap, it's giving “the struct that describes an extended channel info attribute,” and we're gonna do a full vibe check. ✨💖

🌸 NAME 🌸

struct iio_chan_spec_ext_info — Extended channel info attribute. periodt. 🎀

🌈 SYNOPSIS 🌈

here's the exact code shape, bestie — don't let the line wraps scare you, fr fr:

       struct iio_chan_spec_ext_info {
           const char *name;
           enum iio_shared_by shared;
           ssize_t (*read)(struct iio_dev *, uintptr_t private, struct
       iio_chan_spec const *, char *buf);
           ssize_t (*write)(struct iio_dev *, uintptr_t private, struct
       iio_chan_spec const *, const char *buf, size_t len);
           uintptr_t private;
        };

• name — info attribute name. cute and simple. 🎀
• shared — whether this attribute is shared between all channels. highkey important for the group-chat energy. 👯
• read — read callback for this info attribute, may be NULL. so yes, it can be missing, ngl. 😭
• write — write callback for this info attribute, may be NULL. same energy: may be NULL. 💀
• private — data private to the driver. it's giving “driver's own little secret stash.” 🙈
