## Declaration

```occ
virtual IOUSBPipe *GetPipeObj(
 UInt8index); 
```

## Parameters

- `index`: value from zero to kUSBMaxPipes-1

## Return Value

Return Value The IOUSBPipe object. Note that the client does not own a reference to this pipe, so the client should retain() the IOUSBPipe object if necessary.

## Overview

Overview returns a handle to the pipe at the corresponding index
