00017 
00018 <p><i>declared in "ivorbisfile.h";</i></p>
00019 
00020 <p>Seeks to the offset specified (in pcm samples) within the physical bitstream.  This function only works for seekable streams.
00021 <p>This also updates everything needed within the
00022 decoder, so you can immediately call <a href="ov_read.html">ov_read()</a> and get data from
00023 the newly seeked to position.
