Stream seeking interface.
Seekable is implemented by streams (implementations of InputStream or OutputStream) that support seeking. To find the position of a stream, use tell(). To find out if a stream supports seeking, use can_seek(). To position a stream, use seek(). To find out if a stream supports truncating, use can_truncate(). To truncate a stream, use truncate().
