15       command in progress in order to update the streaming buffer.   If  sup‐
16       ported by the driver, all available samples are copied to the streaming
17       buffer.  These samples may be pending in DMA buffers or  device  FIFOs.
18       If sucessful, the number of additional bytes available is returned.  If
19       there is an error, -1 is returned.
