virtual kern_return_t dispatchAbsolutePointerEvent(uint64_t timeStamp, IOFixed x, IOFixed y, uint32_t buttonState, IOOptionBits options, bool accelerate);
```

## Parameters

- `timeStamp`: The timestamp of the event. Use the timestamp of the report element that is the source of the event.
- `x`: The X value, specified in the range 0 to 1.
- `y`: The Y value, specified in the range 0 to 1.
- `buttonState`: The current button state, if any.
- `options`: Additional options for pointer events. Specify 0 for no options. For a list of other values, see doc://com.apple.hiddriverkit/documentation/HIDDriverKit/IOHIDPointerEventOptions.
- `accelerate`: A Boolean value indicating whether to apply the acceleration algorithm to the pointer event. Specify false if you don’t want to apply that logic.
