# NSMachBootstrapServer

A port name server that takes and returns Mach port objects.

```
@interface NSMachBootstrapServer : NSPortNameServer
```

## Overview

Port removal functionality is not supported in [`NSMachBootstrapServer`](/documentation/Foundation/NSMachBootstrapServer); if you want to cancel a service, you have to destroy the port (invalidate the [`NSMachPort`](/documentation/Foundation/NSMachPort) given to [`registerPort:name:`](/documentation/Foundation/NSMachBootstrapServer/registerPort:name:)).

## Topics

[`servicePortWithName:`](/documentation/Foundation/NSMachBootstrapServer/servicePortWithName:)
