# XTaskQueuePort

Declares which port of a task queue to dispatch or submit callbacks to.

## Syntax

```cpp theme={null}
enum class XTaskQueuePort  : uint32_t  
{  
    Work,  
    Completion  
}  
```

## Constants

| Constant   | Description                             |
| ---------- | --------------------------------------- |
| Work       | The work port for the task queue.       |
| Completion | The completion port for the task queue. |

## Remarks

This enumeration identifies the port of a task queue on which to perform an action, such as submitting a callback or getting a port handle. The work port and completion port of a task queue can have independent dispatch modes, and tasks can be submitted to either port. For an example, see [Submitting callbacks](/build/core-features/common/async/async-task-queue-design-howto/submitting-callbacks).

## Requirements

**Header:** XTaskQueue.h

**Supported platforms:** Windows, XBOX One family consoles and XBOX Series consoles
