# getVRAMRange

Return reference to IODeviceMemory object representing memory range of all the cards vram.

## Declaration

```occ
virtual IODeviceMemory * getVRAMRange(
 void ); 
```

## Return Value

Return Value an IODeviceMemory instance. A reference will be consumed by the caller for each call of this method - the implementatation should create a new instance of IODeviceMemory for each call, or return one instance with a retain for each call.

## Overview

Overview IOFramebuffer subclasses should implement this method to describe all the vram memory available on the card. The OS will map this memory range into user space for client access - the range should only include vram memory not hardware registers.
