00035 <dt><i>vf</i></dt>
00036 <dd>A pointer to the OggVorbis_File structure--this is used for ALL the externally visible libvorbisfile
00037 functions.</dd>
00038 <dt><i>i</i></dt>
00039 <dd>Link to the desired logical bitstream. To retrieve the total pcm samples for the entire physical bitstream, this parameter should be set to -1.</dd>

00043 <h3>Return Values</h3>
00044 <blockquote>
00045 <li>OV_EINVAL means that the argument was invalid. In this case, the requested bitstream did not exist or the bitstream is unseekable.</li>
00046 <li>
00047 total length in pcm samples of content if i=-1.</li>
00048 <li>length in pcm samples of logical bitstream if i=0 to n.</li>
