# IOHIDElementCommitDirection

The commit direction for an HID element.

```
typedef enum { ... } IOHIDElementCommitDirection;
```

## Overview

Passing a value of [`kIOHIDElementCommitDirectionOut`](/documentation/HIDDriverKit/IOHIDElementCommitDirection/kIOHIDElementCommitDirectionOut) issues a [`setReport`](/documentation/HIDDriverKit/IOHIDDevice/setReport) call to the device. Before issuing this call, set your desired value on the element with the [`setValue`](/documentation/HIDDriverKit/IOHIDElement/setValue) or [`setDataValue`](/documentation/HIDDriverKit/IOHIDElement/setDataValue) functions.

## Topics
