Structure

IOHIDDeviceQueueInterface

The object you use to access a HID queue from user space, returned by version 1.5 of the IOHIDFamily.

Declaration

typedef struct IOHIDDeviceQueueInterface {
    ...
} IOHIDDeviceQueueInterface;

Overview

The functions listed here will work with any version of the IOHIDDeviceQueueInterface. This behavior is useful when you need to keep track of all values of an input element, rather than just the most recent one.

Note:Absolute element values (based on a fixed origin) will only be placed on a queue if there is a change in value.
