# removeAllBuffers

Removes all buffers from the video stream.

## Declaration

```occ
kern_return_t removeAllBuffers();
```

## Return Value

Return Value kIOReturnSuccess if all the buffers were successfully removed.

## Discussion

Discussion Buffers cannot be removed while the stream is open, as this will change the buffer identifiers of existing buffers.
