# ApuFree

Frees APU physical memory.

## Syntax

```cpp theme={null}
void ApuFree(  
         void* virtualAddress  
)  
```

### Parameters

*virtualAddress*   \_In\_\
Type: void\*

Virtual address to free.

### Return value

Type: void

## Remarks

Freeing the virtual address invalidates the physical address. To create an allocation, use [ApuAlloc](/reference/audio/apu/functions/apualloc).

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

## Requirements

**Header:** apu.h

**Library:** acphal.lib

**Supported platforms:** XBOX One family consoles and XBOX Series consoles
