STRUCT IIO_BUFFER_SETUP_OPS(9)

🎀 struct iio_buffer_setup_ops(9) 🎀

okay bestie, welcome to the Kernel API Manual — this is the page for struct iio_buffer_setup_ops(9), and it’s lowkey just the buffer-setup callback hangout spot. 💖

---

🌸 NAME 🌸

struct iio_buffer_setup_ops — buffer setup related callbacks. That’s the vibe: a struct full of callbacks tied to buffer setup. No cap, that’s the whole name. ✨

---

✨ SYNOPSIS ✨

here’s the exact shape, bestie — don’t let the long line scare you:

struct iio_buffer_setup_ops {
    int (*preenable)(struct iio_dev *);
    int (*postenable)(struct iio_dev *);
    int (*predisable)(struct iio_dev *);
    int (*postdisable)(struct iio_dev *);
    bool (*validate_scan_mask)(struct iio_dev *indio_dev, const unsigned long *scan_mask);
};

---

💅 Members 💅

the whole cast, with exact callback names and their [DRIVER] little badges:

• preenable — [DRIVER] function to run prior to marking buffer enabled.
• postenable — [DRIVER] function to run after marking buffer enabled.
• predisable — [DRIVER] function to run prior to marking buffer disabled.
• postdisable — [DRIVER] function to run after marking buffer disabled.
• validate_scan_mask — [DRIVER] function callback to check whether a given scan mask is valid for the device.
