# IOLittleMemoryCursor

An IOMemoryCursor subclass that outputs a vector of PhysicalSegments in the little endian byte order.

## Declaration

```occ
class IOLittleMemoryCursor : IOMemoryCursor
```

## Overview

Overview The IOLittleMemoryCursor would be used when the DMA hardware requires a little endian address and length pair. This cursor outputs an array of PhysicalSegments that are encoded in little endian format.
