## Header File

Defined in [SDL_audio.h](https://github.com/libsdl-org/SDL/blob/SDL2/include/SDL_audio.h)

## Syntax

```c
void SDL_FreeWAV(Uint8 * audio_buf);
```

## Function Parameters

|         |               |                                                                                                        |
| ------- | ------------- | ------------------------------------------------------------------------------------------------------ |
| Uint8 * | **audio_buf** | a pointer to the buffer created by [SDL_LoadWAV](SDL_LoadWAV)() or [SDL_LoadWAV_RW](SDL_LoadWAV_RW)(). |

## Remarks

After a WAVE file has been opened with [SDL_LoadWAV](SDL_LoadWAV)() or
[SDL_LoadWAV_RW](SDL_LoadWAV_RW)() its data can eventually be freed with
[SDL_FreeWAV](SDL_FreeWAV)(). It is safe to call this function with a NULL
pointer.

## Version

This function is available since SDL 2.0.0.
