# ApuMapApuAddress

> ApuMapApuAddress

Returns a virtual address that is associated with an APU physical address.

## Syntax

```cpp theme={null}
void* ApuMapApuAddress(  
         APU_ADDRESS apuPhysicalAddress  
)  
```

### Parameters

*apuPhysicalAddress*   \
Type: APU\_ADDRESS

APU physical address to map.

### Return value

Type: void\*

Virtual address associated with the specified APU physical address.

## Remarks

This method returns nullptr if the physical address is invalid or if it was not allocated with [ApuAlloc](https://docs.xbox.com/reference/audio/apu/functions/apualloc.md).

The virtual and physical addresses that are returned by `ApuAlloc` represent different views of the same address space.

If the virtual address is known, call [ApuMapVirtualAddress](https://docs.xbox.com/reference/audio/apu/functions/apumapvirtualaddress.md) to determine the associated physical address.
