STRUCT IIO_EVENT_INTERFACE(9)

🎀 struct iio_event_interface(9) — Kernel API Manual 🎀

okay so bestie, this is the Kernel API Manual page for struct iio_event_interface(9) — literally the chrdev interface for an event line. no cap, it’s giving “event line but make it a struct” energy, and we’re obsessed 💅✨

✨ NAME ✨

struct iio_event_interface — chrdev interface for an event line. periodt 💖

🌸 SYNOPSIS 🌸

struct iio_event_interface {
    wait_queue_head_t wait;
    struct iio_event_data *det_events;
    struct list_head        dev_attr_list;
    unsigned long           flags;
    struct attribute_group  group;
    struct mutex            read_lock;
    struct iio_ioctl_handler        ioctl_handler;
};

🧚 Members 🧚

• wait — wait queue to allow blocking reads of events. yes bestie, blocking reads are literally invited 🫶
• det_events — list of detected events. detected events stay booked and busy 💅
• dev_attr_list — list of event interface sysfs attribute. (singular “attribute” stays singular, we don’t edit the source 😌)
• flags — file operations related flags including busy flag. busy flag is giving main character energy 🚩
• group — event interface sysfs attribute group. a whole little sysfs squad 🌸
• read_lock — lock to protect kfifo read operations. protect the kfifo at all costs 🔒
• ioctl_handler — handler for event ioctl calls. ioctl calls got a dedicated handler, slay 💅
