Function libiio_sys::iio_device_attr_read_all

pub unsafe extern "C" fn iio_device_attr_read_all(
    dev: *mut iio_device,
    cb: Option<unsafe extern "C" fn(dev: *mut iio_device, attr: *const c_char, value: *const c_char, len: usize, d: *mut c_void) -> c_int>,
    data: *mut c_void
) -> c_int

@brief Read the content of all device-specific attributes @param dev A pointer to an iio_device structure @param cb A pointer to a callback function @param data A pointer that will be passed to the callback function @return On success, 0 is returned @return On error, a negative errno code is returned

NOTE: This function is especially useful when used with the network backend, as all the device-specific attributes are read in one single command.
