# DispatchSourceMachReceive

A dispatch source that monitors a Mach port for pending messages.

```
protocol DispatchSourceMachReceive : DispatchSourceProtocol, Sendable
```

## Overview

You do not adopt this protocol in your objects. Instead, use the [`makeMachReceiveSource(port:queue:)`](/documentation/Dispatch/DispatchSource/makeMachReceiveSource(port:queue:)) method to create an object that adopts this protocol.
