  870. <p>(Available since SDL 2.0.7) Tell the stream that you're done sending data, and anything being buffered should be converted/resampled and made available immediately. Returns 0 on success, -1 on error.</p>
    871. 

  871. <p>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.</p>
