###### (This is the documentation for SDL3, which is under heavy development and the API is changing! [SDL2](https://wiki.libsdl.org/SDL2/) is the current stable version!)
# SDL_FlushAudioStream

Tell the stream that you're done sending data, and anything being buffered should be converted/resampled and made available immediately.

## Header File

Defined in [SDL_audio.h](https://github.com/libsdl-org/SDL/blob/main/include/SDL3/SDL_audio.h), but apps should use `#include <SDL3/SDL.h>`

## Syntax

```c
int SDL_FlushAudioStream(SDL_AudioStream *stream);

```

## Function Parameters

|                |                           |
| -------------- | ------------------------- |
| **stream**     | The audio stream to flush |

## Return Value

Returns 0 on success or a negative error code on failure; call
[SDL_GetError](SDL_GetError)() for more information.

## Remarks

It is legal to add more data to a stream after flushing, but there will be
audio gaps in the output. Generally this is intended to signal the end of
input, so the complete output becomes available.

## Thread Safety

It is safe to call this function from any thread.

## Version

This function is available since SDL 3.0.0.
